Your reliable JIS Hydraulic Fitting manufacturer

JIS hydraulic fitting factory process

In contrast to the JIC, the JIS hydraulic fitting has a 30° flare and the fitting is sealed with a 30° cone in contact with the seat. JIS hydraulic fittings also offer the following benefits.

  • Good insulation
  • Very flexible in use for dynamic applications.
  • High corrosion resistance for extended service life
  • Can be easily installed in tight spaces
  • Ability to seal hydraulic fluids tightly

What is JIS Hydraulic Fittings?

JIS fittings are commonly used as hose fittings on equipment designed and/or manufactured in Japan and Korea.

What is the difference between JIS and JIC hydraulic fitting?

The standards are different, JIS hydraulic fitting uses the Japanese Industrial Standard and JIC hydraulic fitting uses the Joint Industry Council Standard. Sealing is different, JIS hydraulic fitting uses a Komatsu type fitting installation, while JIC hydraulic fitting uses a 37-degree cone installation.

What does JIS stand for in fittings?

JIS stands for Japanese Industrial Standards. It is the most important and authoritative national standard in Japan and is now widely used in the hydraulic industry worldwide.

How is the JIS hydraulic fitting connected?

JIS hydraulic fitting is mostly used for heavy equipment hose connection, using 30 degrees flare or 60 degrees cone for metal to metal link, also can use o-ring for sealing on this basis.

What are the advantages of JIS hydraulic fitting?

JIS hydraulic fitting is compact and flexible, size and material can be selected, the applicable scenario is flexible, easy to install, not easy to corrosion, and can be used for hydraulic fluid.

What are JIS hydraulic fitting used for?

JIS hydraulic fitting is available for high-pressure connections in the hydraulic field. Widely apply to industry, ship, and mining.

Can BSP hydraulic adapters and JIS hydraulic fitting be used interchangeably?

No, because JIS hydraulic fitting and BSP hydraulic adapters have got different application standards, varying cone diameters, and lengths of threads.

What are the fitting connections under JIS standard?

First,JIS Tapered Pipe Thread
Second, JIS 30° flare (female tapered seat)
Third, Komatsu 30° flare (female tapered seat)
Fourth, Komatsu Style Flange Fitting

What are JIS fitting hydraulic couplings made of?

There can be a variety of materials used to manufacture jis fitting hydraulic, such as steel, stainless steel, brass, etc. You can choose according to the scenario of use.

Is JIS hydraulic fitting reusable?
