Pressure Washer Hose Buyer’s Guide

Pressure Washer Hose Buyer’s Guide

We know searching for the right pressure washer hose can be overwhelming. The first page of Google points you towards all the big box and online stores you can think of. Their options are fine for a casual user who wants to wash his car, but what if you need to something a little more industrial? There are a lot of options and considerations when choosing the right hose. This guide will teach you about them and help you understand what you need.

Is Leaving a Mark Avoidable? Technically, No.

Pressure washer hose is notorious for leaving marks on whatever you’re washing. Dragging a hose across a deck may not always leave a mark, but vibrations from a running pump, alongside the abrasion caused by frequent dragging, will definitely speed up the wear of the cover and, consequently, leave a mark on your driveway or deck.

On the bright side, markings can be reduced by using the right hose. Color, cover material, and proper use can help. Light colored hoses are the best option, with markings standing out less than their black counterparts. Our customers have had the most success with gray. We’ve tried black, blue, and white, all marking more than gray covers.

Synthetic rubbers have the best abrasion resistance, because they are specifically designed to be non-marking. Plastic hoses—like those found at Lowes and Home Depot—are fine when you need a light-duty hose, but they don’t hold up as well.

Size and Length Matters… Duh

Choosing the right diameter is often driven by the port in the pump. Most people choose a 3/8” hose when they have a 3/8” port, a 1/4″ hose with a 1/4″ port, and so on. Using 3/8” hose will provide more pressure and more flow at the gun. This is most important with 1/4″ connections. Pressure drop in a 1/4″ hose can be nearly 400 psi, whereas a 3/8” hose would only give you a 50-psi pressure drop (at 3 gpm in a 100 ft hose).

Keep in mind: the longer the hose, the greater the pressure drop. We don’t want to raise needless concern here, but if you can get away with a 50-footer, don’t buy the 100. More import than pressure drop, longer hoses are hard to handle. If you’ve ever tried to coil a 100-footer with a gun on the end, you know exactly what we’re talking about. We recommend a reel for anything longer than 50 feet, especially if you’re a daily user.

Is It Time To Replace My Hose?

The most common indicator that it’s time to replace your hose is a damaged cover with exposed wire reinforcement. The cover’s job is to protect the wire from corrosion, which leads to reduced pressure as the reinforcement deteriorates. If you can feel a broken wire poking through the cover, it’s time for a new hose. A broken wire is a leak path for water, causing corrosion; and, more importantly, you’re asking for a nasty cut and a trip to the Minute Clinic for a Tetanus booster.

Trust us, we’ve learned the hard way.

Don’t forget to keep a close watch on the hose ends, as they can accumulate rust and calcification on the inside, leading to reduced flow.

Pressure

If you have a 2500 to 4000-psi pressure washer, then feel comfortable using a one-braid, 4000-psi hose. You don’t need to upgrade. More isn’t always better. Industrial-grade, one-braid pressure washer hoses are easier to handle than two-braid. While two-braid hoses are used in 5000 & 6000 psi applications where extra strength is required, they come at the cost of decreased flexibility and increased weight.

Which End Connection Do I Need?

Pressure washer connections typically are either Metric M22 X 1.5 (14mm tube is the most common), 3/8” NPT pipe thread, or straight-through quick connects.  The M22 male thread is found on the pump. From here there may be an adapter to 3/8” NPT or a quick disconnect. Make sure to use some kind of thread sealant like Teflon tape if you have NPT. NPT threads don’t seal by themselves and require help.

*Electric units sometimes have the M22 X 1.5, 15mm threads. There are two ways to determine if you have threads for 14mm or 15mm tubes. One is to measure the inside of the male connection after the taper using calipers. It will be very close to either 14mm or 15mm. The other is to measure the diameter of the male part in the middle of the female threads. This feature, usually with an O-ring, mates up with the taper inside the male threads. It will measure very close and just under 14mm or 15mm.

Cleaning with Chemicals, Detergents, & Hot Water

Sometimes, pressure alone isn’t enough. The surface you’re cleaning might require some extra elbow grease. If you use chemicals, detergents, or hot water, you need a hose that can handle it. Hoses made with plastic tubes are often times good with chemicals and detergents but don’t do well with hot water. Synthetic rubber is engineered to handle a wide range of industrial cleaners and handle hot water. Hoses rated to 311°F will provide the longest life if you routinely use a heater in your washer system. Heat and chemicals can quickly break down your hose.

Let me tell you a story:

We were once selling a “water cooling” hose to a steel mill. The application was only 160°F, so we chose a common water transfer hose rated for 180°F. This was the same rating as the equipment manufacturer’s hose, so we felt comfortable replicating the spec.

The manufacturer’s hose lasted three months, and so did ours.

At first, we didn’t even think temperature mattered; after all, our hose was rated for the application. After some investigation, we decided that temperature might be our culprit. We specced a 350°F hose ten years ago, and it’s still going strong. This taught us a valuable lesson: hot water can wreak havoc on your hose, and if you have a burner, you need a hose specifically designed for hot temperatures.

Understanding Foreign Threads in the Hydraulic Industry

Understanding Foreign Threads in the Hydraulic Industry

Understanding Foreign Threads In The Hydraulic Industry

In an ever-changing world, it is hard to ignore the increasing amount of foreign threaded connections in the hydraulic industry. Whether it is in a port connection, to a hydraulic hose, even lubrication and grease fittings, they seem to be in all areas of a hydraulic application. Understanding foreign threaded connections can be very cumbersome, and confusing! But being able to understand, and more importantly identify foreign threads can make the difference on whether a customer purchases from you again or goes to the competition.

With the increased amount of goods purchased from over-seas manufacturers, it only makes sense that those goods will have foreign threaded connections. Essentially, there are only three countries that still use the Imperial System; The United States of America, Liberia, and Myanmar (formerly known as Burma). So, it’s no wonder why foreign threads are more prevalent than ever in the hydraulic industry. Here is a list of the most common Foreign threads in the Hydraulic Industry.

British Threads

The two types of British Threads are, Parallel (BSPP) and Tapered (BSPT). British Parallel threads are commonly referred to as a “G” thread, whereas British Tapered threads are referred to as “R” thread. They are measured in Nominal Sizes, and the threads are measured in Threads per Inch.

There are three sealing methods to a BSPP thread. This thread can seal using the BS 5200 60° Cone-Seat, which is like how a NPSM thread will seal, with an external Gasket, or the ISO 1179 O-Ring. These gaskets can include Bonded Seals, O-Ring and Washer combination, and Elastomeric Seals. The O-Ring Only Style is exclusive and will only seal with the correct size O-Ring, like the SAE J514 Straight Thread O-Ring Boss.

The British Tapered threads are only intended to seal on the flanks of the threads, like how a NPT thread seals, and are generally seen on lower pressure, or schedule pipe, applications.

Metric (DIN) Threads

There are also two styles of Metric Threads, Parallel or Tapered. Metric threads are measured, in millimeters, on the outside diameter and pitch of the threads. Generally, there are 3 thread pitches in metric fittings, pertaining to the hydraulic industry; 1.0, 1.5, and 2.0.

Just like the British Parallel threads, Metric Parallel threads can seal in one of three ways. Either, it can seal on the 24° Tube Seat, like an Ermeto® fitting, it can seal with an external gasket, or with the ISO 6149 O-Ring. The external gaskets are alike to the British Parallel style Bonded Seals, O-Ring and Washer combination, and Elastomeric Seals, ignoring the true size of the seal. The ISO 6149 O-Ring Only style is exclusive and will only seal using the correct O-Ring, like the SAE O-Ring Boss style previously explained.

Metric Tapered threads are generally seen in low pressure, and lubrication applications. They are intended to seal on the flanks of the threads, like NPT threads.

Japanese (JIS) Threads

Japanese threads, or JIS, are easy to understand. They are nominally sized, and the threads are measured in Threads per Inch. JIS threads are the exact same size, pitch, and thread count as British threads. The only difference is that JIS has a 30° outward flare, similar to the 37° flare that we see on JIC fittings. There are more Japanese threads that exist in hydraulic systems, but to keep things as “easy” as possible, we will not go over those at this point.

Komatsu Threads

If this isn’t confusing enough, Komatsu threads tie in Metric thread pitch along with the JIS 30° flare. Komatsu threads are only ever used on Komatsu made machinery. Which is why when identifying threads, it never hurts to ask what kind of machine that the thread originates from.

5 Most Common Types of Hydraulic Hoses

Hydraulic hoses of any type must meet very stringent standards to adapt to the pressure levels, loads, and sometimes contorted positions demanded of them. Few engineering components are expected to withstand the forces within and be flexible enough to bend or reach at varying angles to perform heavy-duty functions.

In simplest terms, a hydraulic system is one that uses highly pressurized hydraulic fluids to create mechanical output such as lifting, stamping, or forging. Hydraulics are commonly used for excavators and backhoes, wing flaps on airplanes, lifting equipment like jacks and wheelchair lifts, and much more.

Standard industrial hoses are not suitable for use in hydraulic systems. Hydraulic hoses, as part of an enclosed system, must be able to withstand average internal pressures averaging 3000 psi and withstand extreme temperatures.

 

Standards for Hydraulic Hoses

SAE, the standard-setting organization of engineers, has set standards for hydraulic hoses. Since these components are essential to efficient operations and, in many situations, human safety, hoses must meet specific requirements for a hydraulic system. SAE J517 provides general, dimensional, and performance specifications for hydraulic hoses in mobile and stationary systems.

The typical hose is composed of three layers. These include the inner tube, a reinforcing middle layer, and a protective outer layer.

The design and material used for the inner layer must be engineered to the level of flexibility required and the type of fluid to be used. Typically, the inner layer is produced from a form of synthetic rubber, thermoplastic, or a PTFE material.

The middle layer which largely determines the strength is made from coiled wire or a textile braiding that allows flexibility, yet is strong enough to withstand the extreme pressures of a hydraulic system at work.

The outer layer is a material that protects against foreign matter, extreme weather, abrasive tools, and sharp objects.

Fittings that attach the hydraulic hose to its source and destination must be sufficient to manage extreme pressure as well.

 

5 Types of Hydraulic Hoses

While there are more types and applications of hoses, the five listed here are a cross-section of specific components, uses, and capabilities:

  • SAE Standard Hose: SAE 100R1 is a high-pressure hose is used with petroleum or water-based fluids designed to power general industrial applications. The hose is single steel, wire-braided tubing that will operate in temperatures ranging from -40°C to 100°C.

 

  • Standard High-Pressure Hose: These hoses are flexible and used to transporting mineral and hydraulic oils and water-oil emulsions. They are in demand for the mining and oil industries, construction, and agriculture.

 

  • Low-Pressure Hose: Textile-braided and highly flexible, these hoses are employed in lighter applications such as return lines, anti-static delivery lines, and air or lube lines. Low-pressure lines are not suitable for braking or other safety-related applications.

 

  • Steel Wire-Braided Hose: Either single or double wire-braided and extra durable, these hoses are used to transport fluids under extreme pressures, temperatures, and even a vacuum. These hoses are used in oilfields, mining, and heavy industrial applications.

 

  • Thermoplastic Hydraulic Hose: Useful for heavy construction, hydraulic lift equipment, and lubrication lines, the thermoplastic hoses are resistant to abrasion and can operate at very low temperatures. Both the inner and outer layers consist of a thermoplastic material while the middle layer reinforces with a synthetic fiber mesh.

 

Choosing the Right Hose

Hydraulic hoses might be at the core of your operation. Breakdowns can be expensive. Determining the best ones for your pressure capacity, durability, flexibility, abrasion resistance, temperature exposure, and the material to be conducted usually requires complex engineering considerations.
