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.
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.
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.

Hydraulic hoses must be durable and long-lasting enough to handle the needs of the particular function. Hydraulic hoses, unlike many other industrial hoses, need substantial reinforcement to endure the significant pressures that are necessary to perform their job. Reinforcing support can come in many forms depending on the levels of pressure, materials, and other factors that the hose will be required to withstand.
Consider STAMPED When Selecting Hydraulic Hoses
When determining which hydraulic hoses and fittings will be right for your situation, TCH Industries of Twinsburg, Ohio, suggests considering the acronym “STAMPED.” Seven questions cued by each letter will help identify which hydraulic hose is right for your situation. These are:
- S: Size and diameter of the hose. Not only does this refer to the internal diameter of the hose but also to the required length from port to port.
- T: Temperature refers to the maximum and minimum temperatures that the hose will withstand during all parts of the process.
- A: Applications refers to the actual use of the hose and equipment. Will this be for industrial use or injection molding, for example.
- M: Media refers to the liquid, gas, or solid that will be conveyed. Different medias require different levels of strength to accommodate what will be moving within.
- P: Pressure is a critical variable in hydraulics. Pressure is the force that moves and lifts, so factoring the degree of pressure that the hose will need to withstand is essential.
- E: Ends of the hose will be determined by where the hose will connect. The origination and destination ports may be different so the assembly might require different connecting hardware.
- D: Delivery dates may be requested. These may depend on testing, certification requirements and, perhaps, custom production times.
Dealing with High Pressure
Hydraulic hoses, more than any other, are expected to withstand higher-than-normal pressure while in full operation. As a result, added reinforcement becomes mandatory.
TCH Industries offers hydraulic hoses that can withstand up to 10,000 psi, working pressure, as well as other hoses, fittings, and accessories for low and medium pressure scenarios.
The type and degree of reinforcement are calculated by the working pressure of the hydraulic system. As the pressure increases, the PSI rating of the hose must increase as well.
Most hydraulic hose reinforcement material may be one of three types, although combinations of these are often used to bolster the pressure capacity. These materials are:
- Braided synthetic textiles, wire, and other materials set in a crisscross, overlapping pattern that allows for flexibility and maximum strength.
- Spiral Wrapping with wire, textiles, synthetic materials consisting of parallel, rather than overlapping reinforcement. This pattern strengthens the hose while allowing for lower flexibility.
- Helical coil (a helix pattern) strengthens the hose to prevent it from collapsing inside when suction or a vacuum is applied. The coil is often used in conjunction with the braided textile reinforcement to manage both high and low-pressure situations.

Eventually, just about every component of a production line wears out and must be replaced. Waiting until too late can result in a catastrophic event plus a considerable loss of time, product, and money.
Replacing brewery hoses and tubing before they become a problem will keep the operation running smoothly. Moreover, you can also avoid those inevitable warnings from the FDA inspector regarding frayed or cracked hoses with leak potential.
If your brewery has been producing for several years and maintenance records have been carefully maintained, it is possible that you could predict the frequency with which the hoses need to be replaced. Of course, in a high-speed, multi-faceted business, tracking hose and tubing life may not be a top priority.
Outsourcing that responsibility can be the most efficient and least expensive way to manage this responsibility. Trained and certified technicians can perform periodic inspections, make adjustments where needed, and recognized a potential FDA host failure before it happens with a visual inspection in addition to a historical performance review.
One company, TCH Industries in Twinsburg, Ohio, near Cleveland, offers a Normal Wear Replacement Plan designed to eliminate any concern for potential hose failure. With hydrostatic pressure testing for brewery, winery, or food production hoses and tubing, trained technicians will come to your location to test and repair, if possible, to extend the useful life of any conduits that are beginning to show signs of wear.
Detecting Warning Signs
Inspection for hose deterioration should involve looking for any excessive wear that may expose the reinforcing wire layer within. Excessive cover wear and leakage near the fittings may be a clear sign that trouble might be brewing and replacement or repair is essential. Leakage near the joints could relate to worn gaskets or O-rings, as well.
Additionally, inspecting the interior of the hose with a flashlight may reveal blemishes, excessive wear, or obstacles lodged within that could retard the flow of fluids.
Extending FDA-Approved Hoses with Sani-Saver
When performing an onsite survey, a TCH Industries certified technician may recommend reinforcing your somewhat worn hoses with Sani-Savers. These attachments act as a donut encompassing the hose to prevent further cover wear and keep the system looking clean and sanitary. Maintaining a spotless appearance is critical for both the FDA inspectors and customers who can see the brewery in action. Often, Sani-Savers are installed near the sanitary hose ends to protect the stainless fittings from damage should they be dropped. Stainless Steel Tri-Clamp, I-Line or Bevel-Seat, fittings are very costly components of an FDA approved hose assembly.
Replacing Brewery Hoses
TCH Industries partners with more than 30 world-class manufacturers of industrial and hydraulic hoses, fittings, and accessories. The company stocks FDA-specified industrial hoses and tubes designed specifically for food and beverage production.
In addition to their extensive line of hoses and tubings, TCH Industries has all of the accessories to operate a clean FDA-approved beverage line. Fittings, bumpers, and indicators can be incorporated to eliminate bacteria development and maintain a favorable cosmetic appearance.

Industrial hoses and the appropriate fittings and accessories are essential components in almost any type of production. Managing the precise flow rates while providing flexibility for conveying liquids, solids, and gases, custom designed hoses fill the need for just about all industrial, chemical, hydraulic, sanitary, brewing, and other applications.
The design of the appropriate industrial hoses and fittings depends on the job to be performed. Every industrial hose application is unique and may involve a liquid, solid or gas with objective to transfer the material from pt A to pt B. Some hose construction requires additional layers of reinforcement, insulation, and protection, and may include combinations of materials that include rubber, metal, and PTFE.
What Happens When Industrial Hoses Fail?
A failed hose can stop an entire production line, either because it is conveying an essential component, providing necessary force or lift as in a hydraulic line, providing refrigeration or sanitation.
In case of a hose break or malfunction, the first step is to disconnect and remove the faulty hose assembly from service. Disconnecting the hose may mean shutting down an entire production line for a time while the situation is remedied. Every minute of lost production can result in significant unnecessary expense.
The principal objective to fix or replace the unit before it fails, not after.
Regular Inspection and Preventative Maintenance
As with any mechanical operation, preventative maintenance and frequent inspection are essential. At some time, inevitably, any hose assembly will need to be replaced due to normal wear and tear. Regular inspection and replacement of hoses used in critical applications will eliminate unexpected downtime. Waiting until a problem occurs is a catastrophic approach since a broken hose and assembly can result in peripheral damage or even injury.
You must begin by looking for any obvious cosmetic issues such as excessive exterior cover wear or exposed reinforcement wire within. To avoid a problem, replacing worn hoses is essential. If the hose and fitting are relatively new but have not reached their expected useful life, contact your supplier for an alternative. A more durable hose may be the best solution.
When ordering a replacement, the following parameters for identifying the best industrial hoses and accessories for your situation are:
- Size: What is the diameter and length of the required hose from fitting to fitting?
- Temperature: What will be the maximum and minimum temperature of the material media being conveyed?
- Application: How will be the hose be used?
- Media: Will the material passing through be liquid, gas, or solid?
- Pressure: What will the PSI level of the material being conveyed?
- Ends: What type of ends or connections will be needed?
- Delivery: When will you need the assembly?
In some cases, hoses suspected of being overused or worn out can be tested and repaired to a like-new condition. Make sure the supplier has this capability and can give assurances that the restored hose is fully operational.
The most effective industrial hoses suppliers, like TCH Industries in Northern Ohio, offer testing and repair as well as a normal wear replacement plan as part of their hose installation.
