Hydraulic fittings can be applied in a wide range of applications. As long as there are hydraulic systems in the applications, there is a definite need for hydraulic fittings. Different sizes, materials, and types of fittings are used in different environments. In general, these areas will require the use of fittings:

Agriculture: Tractors, harvesters, and irrigation systems all need hydraulic adapters.

Industry: Hydraulic systems are present in most equipment in industrial applications, so hydraulic fittings are present to keep the system running properly.

Construction: Excavators, bulldozers, and other large machinery and equipment require high-quality hydraulic fittings.

Oil and gas: Transporting and storing oil and gas requires hydraulic fittings that do not create leaks.

Marine: Marine transportation or offshore oil wells require corrosion-resistant, strong-sealing hydraulic fittings.

Transportation: Many industries will need to transport materials, so hydraulic piping can ensure the safe transportation of fluids under pressure.

Automotive: There are specific standard fittings for brake systems and fuel systems in automobiles. These fittings ensure the proper operation of the system.

The right size corresponds to the right installation for the right application.For example, imperial sizes are 1/8′, 3/8′, and 1/2′. Metric sizes are M8*1.0, M10*1.0, and M22*1.5, etc. American sizes are 1/8, 1 1/4, and 2, etc. When selecting a fitting, choose the fitting size carefully.

Each hydraulic fitting has its own characteristics, but some of them are not very obvious, so how to distinguish them?

First, observe the shape.

If one end of the fitting is a tube and the other end is threaded, then this is a hose fitting; if both fitting ends are threaded, then it is a hydraulic adapter. A fitting with three ports is a tee, and one with four is a cross fitting; The body of the swivel fitting can be rotated in all directions, and the sleeve of the reusable fitting is removable, while the one-piece fitting is a whole part.

Next, use a thread gauge.

Some threads can be observed visually as straight or tapered threads. For example, BSPT and NPT are tapered threads. BSPP and UN/UNF are straight threads. If it is difficult to observe, use the corresponding thread gauge to check.

Then you can use a pitch gauge to measure the pitch.

Use vernier calipers to determine the size of the fitting, or the inside(I.D) and outside diameter (O.D)of the fitting.

If you really can’t identify what type of fitting you have, check your supplier’s data, or contact us directly!

Hose fitting

Inspection: Check the appearance of the fitting before installation to make sure the threads are free of burrs, rust, and breakage.

Cutting: Cut the hose to the proper length.

Installation: Install the hose end of the fitting into the hose and tighten the nut to form a hose assembly. For crimp fittings, use a crimper to secure the fitting.

Test: Test for leaks in the hydraulic system.

Hydraulic adapter

Inspection: Check that there are no scratches, burrs, or breaks on the adapter.

Installation: You can apply a little lubrication to the adapter, use a wrench, and screw the fitting into the installation position. If the fitting has an O-ring seal, make sure the O-ring is not broken. And make sure the O-ring is installed in the correct position.

Testing: Test the assembly to make sure there are no leaks in the hydraulic system.

In addition, there are some special fittings: welded hydraulic fittings. These types of hydraulic fittings require professional installers to weld them.

Raw material purchase – Raw material processing – CNC Lathe processing – Surface treatment – Inspection

Hydraulic fittings are generally processed using hot forging, which greatly improves the strength and toughness of the fittings.

In CNC lathe processing, the fitting will go through several steps, including punching, profile processing, and thread processing.

After the fitting is processed, it needs to undergo surface treatment to improve the aesthetics of the fitting. Common treatments include galvanizing, pickling, grinding, polishing, etc.

All fittings of Topa are inspected several times for appearance, threads, and quality. Topa factory uses salt spray testers, pulse testers, and other instruments for this purpose.

Some hydraulic fittings can be sealed directly by the metal surface, or by O-rings. Except for this type of fittings, others need some external help.

Teflon tape: can be wrapped directly around the threads to create a seal during installation; NPT threads often require tape to create seals.

Sealant: Loctite liquid thread sealant can be applied directly to the threads. When the fitting is used in a hydraulic system, it can directly seal the gap between the fitting and the component connection.
