HOW LONG CAN A PRESSURE WASHER HOSE BE?

To keep a long story short—or a short hose long—the easy answer is that your pressure washer hose can be whatever length is needed. We typically supply our assemblies in twenty-five-, fifty-, and one-hundred-foot lengths with ends and bend restrictors included.

That being said, there are options, such as straight-through quick disconnects to extend the length of your assembly or even allow you to easily connect 2 hoses together. When you need to park in the front of the house, we can ensure you have ways to extend your assembly from the hose reel in your truck to your customer’s backyard.

DO YOU LOSE PRESSURE WITH A LONGER HOSE?

There are many considerations when learning how the length of the hose can impact the pressure rating of your assembly. In a best case scenario, when working in normal operating conditions on flat ground, the drop in pressure per extended length of hose is not significant. We all know that operating conditions are very rarely normal, and we often find ourselves working in unique environments.

The chart below from Danfoss Weatherhead will elaborate more on these drops in pressure. As you will see, the friction between the water and the hose is exponentially increased as the length of the hose is increased. This is what leads to pressure loss in a hose assembly.

CAN YOU CONNECT TWO PRESSURE WASHER HOSES TOGETHER?

The simple and short answer is yes. But you’ll need the right equipment to do it efficiently, and with minimal pressure loss. If you ever find yourself in a situation where your setup doesn’t grant the length you need for the job, that doesn’t always mean you need to purchase an entirely new assembly. As we mentioned before, we offer straight-through quick disconnects to connect more than one assembly to help get the job done right!

ARE POWER WASHER WANDS UNIVERSAL?

As with many products in the industry, we see many proprietary accessories and fittings that can’t easily or safely be replicated. The same can be said for power washer wands. Depending on your application and the pressure washer gun your using, you may be required to use wands and attachments made specifically for your equipment. Because of this, TCH Industries strives to stock a wide variety of power washing attachments to fit your application.

 WHAT SIZE ARE PRESSURE WASHER FITTINGS?

Many of the ends, adapters, and quick disconnects that we supply with our assemblies are 3/8″. Which is why TCH Industries’ PowerKlean4000 pressure washer hose with a 3/8” inside diameter.

In the pressure washing industry, it is very common to see metric M22X1.5 threads. The outer diameter is 22 millimeters, with a metric 1.5 thread count, on the male end.

However, the female end has an inside diameter of 20.5 millimeters, but still has the metric 1.5 thread pitch, and generally has an O-ring to prevent leaking. These threads are common on pumps, hoses, and spray guns. And normally have a black plastic nut on the female end. With the right adapter, these can easily be couple with quick connect fittings.

CAN YOU USE A 100-FOOT GARDEN HOSE ON A PRESSURE WASHER?

It all depends on if you are using it for the inlet or outlet of the pressure washer.

If you are using it on the inlet side, the answer is yes you can use a 100 ft garden hose. But there are going to be some drawbacks compared to using a shorter hose. As mentioned before, a longer hose will slowly begin to decrease water pressure. Which may lead to starving the pump of water. This will lead to a reduction in the water on the outlet end and may even damage the pump.

If you are using a garden hose on the outlet, or pressure side, the answer is a very big NO! Pressure washers operate at a much higher PSI than a standard garden hose is rated for. Doing can, and more than likely will, lead to the hose bursting once it becomes filled with water. As a result, this can lead to increased down time or even injury.

We recommended using a 3000 psi, 4000 psi, or 4500 psi power washer hose. These high-pressure hoses will make sure you get the job done right the first time. TCH Industries’ PowerKlean 4000 hose is a kink resistant, non-marking, abrasion resistant, and steel wire braided reinforced. Which is perfect for pressure washing replacement hoses.

HOW MUCH PSI DO I NEED TO CLEAN CONCRETE?

We could say this for almost any question asked, but it’s the truth. Certain situations you face are going to require a different answer. However, the general rule of thumb is that 3,000 PSI, with a flow rate of 4 gallons per minute, is the right pressure to clean up concrete. 

HOW DO I PRESSURE WASH WITHOUT A PRESSURE WASHER?

Pressure washing without the added PSI of a pressure washer defeats the purpose. However, we do have a few options to give a similar effect. Wand attachments can be used to restrict flow. Which will increase the velocity of the water coming out of the wand. Take the reference below for example.

When you turn on your water to your garden hose, with nothing covering the end, it will simply flow out at a low velocity. Which is why the water flows out of the orifice and does not go very far. But once you put your thumb over the end, the water shoots much further.

It’s easy to think that the PSI has somehow magically increased dramatically by doing this. But the answer is that the PSI has remained the same, you just reduced the orifice size that the water comes out from. This leads to a dramatic increase in the velocity of the water, which is why it shoots out much further.

You can use the wand attachments to get a similar effect. With the right attachments, you can also change out the nozzle tips for different angle while spraying.

Spray Tip Nozzles

WHAT PSI IS SAFE FOR WASHING CARS?

Power washing cars is a safe and effective way to get your (or your customer’s) vehicle in pristine condition. But unlike other applications, you need to be more mindful of pressure ratings when using your pressure washer on a vehicle.

If you use a 3000-PSI—or higher— pressure on a vehicle, you can easily damage the paint. For these jobs, you’ll want to stay closer to the 1000 – 2000 PSI range. The majority of pressure washers have a pressure reducing valve, which will need to be adjusted accordingly.

HOW MUCH PSI IS A GARDEN HOSE NOZZLE?

Typical garden hose nozzles are rated for 200 PSI. TCH offers a wide variety of nozzles, with higher end models that can reach 400 PSI before bursting. But just because your nozzle is rated to 400 PSI your hose may not be. This is a very easy misconception in the fluid flow industry. Make sure you contact the professionals at TCH Industries to get the right nozzle for your assembly.

Hydrostatic Testing

Hydrostatic Testing

Hydrostatic Testing

In this blog, TCH Industries is going to be going over what is hydrostatic testing for a hose, how does hydrostatic testing work, and how to preform a hydrostatic test.

What is Hydrostatic Testing

What is Hydrostatic Testing for a Hose?

Hydrostatic testing is the process of pressurizing a hose or pressure vessel with water to a specific pressure. Holding the pressure for a duration of time, and testing for strength and leaks. As a result, hydrostatic testing is a way of ensuring that a hose or container (such as storage tanks) will be able to retain the pressure that the item is rated for. And that it will not leak or fail once pressurized.

There are times when proof testing is required. A proof test is a typically performed at 1.5x the rated working pressure. As a result, this will confirm the hose assembly meets the pressure rating of the assembly. Hydrostatic pressure testing will also ensure that the ends have been safely and properly fitted, and that the assembly is leak free.

According to NAHAD–The Association for Hose and Accessories Distribution–the following are required when testing is performed:

 

HOSE TYPE PRESSURE REQUIRED TIME
Industrial Minimum 1-½ times working pressure for assemblies unless otherwise required by the customer or designated hose specification. 5 minutes
Hydraulic 2 times working pressure unless otherwise required by the customer. 30-60 seconds
Composite 1-½ times working pressure unless otherwise required by the customer. 1-4” nominal bore: 5 minutes
Fluoropolymer 1-½ times working pressure unless otherwise required by the customer. 1 minute
Corrugated metal Contact the manufacturer for maximum test pressure for each hose. Contact the manufacturer

How Does Hydrostatic Testing Work?

Before we get started on hydrostatic testing, it’s important to understand what kind of equipment is required. Depending on the type of test, a hydrostatic pressure test requires a pump or power source. These can include a hand pump, power driven hydraulic pump, or an accumulator system. We recommend, as does NAHAD, that the test is performed in a test tank. Just like the one shown below.

Hydrostatic Tester

NAHAD: For assembly testing, the rating of the component with the lowest rated working pressure determines the working pressure of the assembly. For example, If you have a 3,000 psi hose, but the ends are only rated for 2,000 psi, the entire pressure rating of the assembly is rated to 2,000 psi.

What Are Signs of Failure in a Hydrostatic Test?

  • Weeping/leaking
  • Excessive elongation of hose
  • Hose barb not properly retained, slides out of assembly
  • Bubbles form in cover or pinholes leak
  • Hose burst

How to Perform a Hydrostatic Test

As we have said a few times already, we’ll be referring to the NAHAD guide for the step-by-step process on how to properly preform a hydrostatic test:

 

  • Ensure that your hose is as straight as possible, and slightly elevating one end of the hose. This will ensure any trapped air is expelled.
  • Cap or plug one end of the hose assembly.
  • Completely fill the system with water. Doing so will ensure that the water level will expel all trapped air inside the hose.
    • It’s extremely important to use a bleed valve to release trapped air in a pressurized assembly, as a safety measure. Failing to do so will result in the expansion of air compressed in the hose when released suddenly, and can result in serious accidents.
  • After that, mark a reference line behind the fitting at the end of the ferrule, clamp, band, etc. This will help with identifying any elongation of the hose, or coupling slippage. 
  • Once the prior steps are completed successfully, gradually raise the pressure to the desired rating. Hold at this pressure for the time indicated in the chart referenced above. Meanwhile conducting a visual inspection of the assembly. While the pressure is rising, watch for deformation, leakage, and coupling slippage. Any of which will be cause for rejection.
  • While testing, the assembly should be totally leak free for the entirety of the test.
    • According to NAHAD, leakage is defined as a continuous stream of water droplets emitted from a single or multiple locations.
  • Finally, after the test is completed, relieve the pressure before disconnecting and drain the water from the hose.
Pressure Relief

What is the Difference Between Hydrotest and Hydrostatic Testing?

Hydrostatic testing can be easily confused with hydro testing. Hydro testing is more commonly used in pipe applications, such as pipelines for plumbing or oil and gas pipelines, fuel tanks, and other piping systems. Water is run through the system at a predetermined PSI to identify leak points. Hydrostatic testing, as we mentioned before, is the process of water pressurizing a hose or container with water to a predetermined high pressure to verify its structural integrity.

How To Use Teflon Tape

How To Use Teflon Tape

As simple as it seems, there is a right way to apply Teflon tape. Doing so can ensure your fittings seal properly and your connections won’t leak.

How to use teflon tape

The Right Way to Apply Teflon Tape

When you begin the application, start the tape on the second thread and apply clockwise. Doing so will help prevent cross threading and ensure tape does not end up inside the pipe. Once you have your proper placement, keep the tape tight and continue wrapping three times.

 

A standard pipe fitting will seal properly after you have threaded it in about a half an inch or so, depending on the size. Because of this, the most commonly used thread tape is half of an inch in width. Keep this in mind when applying the proper amount of plumbers tape and let this serve as a starting point on how far to thread in your pipe fittings.

Right way to apply Teflon tape

How to apply Teflon tape clockwise

You may find yourself asking ‘how do you apply thread tape clockwise’? Once you know how, it’s pretty simple. Hold the thread in your hand and aim it at your eyes. While looking at the thread from this perspective, apply the tape in a clockwise manner.

The Wrong Way

As easy as it may seem, there are wrong ways to apply tape to pipe threads. As mentioned before, don’t cover the first thread. Doing so can lead to pieces of the thread seal tape contaminating your system. Also, if the tape is applied counter clockwise it will functionally unwind as the part is threaded together. Clockwise helps the tape to tighten as it is threaded together

wrong way to use Teflon tape

When Do You Use Teflon Tape?

Teflon tape is a standard for many different applications. These include air fittings, natural gas lines, propane, water, and plumbing, just to name a few. Occasionally you will see a color-coded system for more volatile applications. Yellow is used for gas pipe fittings where natural gas is involved, whereas green is for oxygen lines and applications. Being virgin Teflon, green tape contains no oil or contaminants. This helps to prevent combustion from happening.

When Not to Use Teflon Tape?

There are many instances of Teflon tape being used on improper applications. For example, many hydraulic fittings such as JIC are seen with thread tape. However, the seal on a JIC connection is formed on the 37° metal to metal cone seat and not on the threads. PTFE tape doesn’t help with this seal and can create unnecessary leak points, not to mention the possibility that it will contaminate your hydraulic system.

JIC Cone Seat

Conclusion

Think about your connections before applying Teflon tape. Ask yourself if the seal is made via threads or another method, such as an O-ring or compression. This can help make sure you only apply thread tape where appropriate.

 

Plastic fittings, as opposed to metal pipe, are another great example of when to be careful about your usage of Teflon tape. The tape acts to reduce friction and makes it easy to over torque. Because plastic is fragile, over torqueing can cause the fitting to crack. 

 

TCH Industries offers a wide variety of Teflon tape, including higher density tapes.

 

Keep these tips in mind when you ask yourself how to apply Teflon tape, and you’ll have your connections more secure than ever before!

Hose Length Tolerance

Hose Length Tolerance

Hose Length Tolerance

The Hose Pro’s at TCH Industries explain what are the tolerances in hydraulic hose lengths, and how to proporly measure hose assemblies.

5 Misconceptions Video

Tolerances in Length of Hydraulic Hose Assemblies

Unless specified by your customer, hydraulic hose assemblies are measured from end to end. The only exception being assemblies with O-ring face seal end connections, in which they are measure from seat to seat. Make sure when measuring these assemblies that you pull back the nut to reveal the seat to achieve a proper length. If the end on the assembly is a 90- or 45-degree fitting, make sure the measurement cuts through the center of the angle. When you’re screwing into a port using a 45- or 90-degree fitting, you can come up short or long if you don’t measure through the center line. Considering jump sizes, the nuts on your end connections can be larger or smaller, so you need to make sure you are consistent. Please see the image below for a visual reference.

How to measure a hose correctly

Hydraulic Hose Length Tolerance

NAHAD lists the tolerance, determined by length, as shown below:

 

Tolerances for a hose up through 12 inches (304.8 mm) = 1/8″

 

A hose measuring 12 through 18 inces (304.8 through 457.2 mm) = 3/16″

 

A hose length of  18 through 36 inches (457.2 through 914.4 mm) = 1/4″

 

A hose assembly longer than 36 inches (914.4 mm) = 1% of the overall length

 

TCH Quick Tip

When building a hydraulic hose, it’s easy to cut the hose, insert the ends and measure to the length we’re looking for. For example, we cut and inserted ends to achieve a hose that was precisely twenty-six inches long, which grew nearly half an inch after crimping.

We measured a hose end-to-end at precisely 26 inches, using Danfoss’ H43020-100, 1-1/4-inch hose, along with their 4S-style 1-1/4-inch male JIC and male NPT end connections. After crimping, the hose assembly measured at just under 26.5 inches, nearly one-half of an inch in length.

When you crimp the ends on, the hose is going to grow, and this is something you need to keep in mind with assemblies, especially when the OAL is critical.

5 Misconceptions in the Fluid Conveyance Industry

We at TCH Industries understand that the fluid conveyance industry is very confusing, and can be very misleading. Here is a list of 5 misconceptions that we see almost everyday. Click on the video for a Hose Pro to explain them the best!

5 Misconceptions Video

Minimum Bend Radius Vs. Force to Bend

A nominal bend radius can be easily misinterpreted as a hose’s ability to flex. When comparing two hoses with the same I.D. and minimum bend radius, you’ll find they don’t flex quite the same. Tube, cover, and reinforcement construction are the three main attributes that can determine a hose’s ability to flex. We recommend, if a hose’s ability to flex is important in your application, to get your hands on the hose to see what works for you.

Remember: Don’t confuse minimum bend radius with a hose’s ability to flex.

Teflon Tape on SAE Threads

It’s a very common misconception to believe that Teflon tape will improve any thread connection. On tapered threads it is acceptable to apply Teflon tape, but for parallel threads this is just not the case. Take JIC threads for example; the seat, or seal, is achieved on the 37-degree surface angle. On pipe thread, the seal is achieved via metal-to-metal wedging. When you apply Teflon tape to pipe thread, it lubricates the threads, also acting as an anti-seize for future maintenance.

Threaded connection with male and female halves

Hose Assembly Pressure Rating

Just like a hose consisting of multiple components-tubing, reinforcement, cover-a hose assembly is a combination of multiple parts. Let’s say we’re building a 2″ assembly with 2″ stainless steel cam & grooves on each end, but it has to be 500 psi. We find a hose-Parker 7107, rated to 500 psi-perfect! However, our stainless-steel cam and groove ends are only rated to 250 psi. This means regardless of the pressure rating of the hose we specced, our assembly is only rated to safely operate at 250 psi, due to our end connections.

Let your customer know: The lowest rated component of the assembly is the max working pressure.

BSPP is NOT Metric

Things can get hairy when metric threads come into play. We commonly see BSPP called out as a metric thread, when someone is specifying their adapters or hose ends. However when you think about it, British Parallel Pipe is measured in threads per inch and the outside diameter is measured in fractions of an inch. Inches are not metric. Metric threads are measured in millimeters per thread and are measured by the outside diameter of the threads in millimeters.

Threaded connection with male and female halves

Tubing and Hose

When talking about tubing and hose, it’s important to remember two things: hose is measured by I.D.-Inside Diameter, while tubing is measured by O.D.-Outside Diameter. Let’s say you’re brought a brake line that’s 3/8″ O.D. steel tubing. To correctly convert this to a hose assembly, you’ll want to use 3/8″ I.D. hose.
