What is JIC hydraulic fttings?

JIC hydraulic fittings have a 37° cone seat on the female fitting and a 37° flare on the male fitting. Common in hydraulic systems. for conveying fluids.

What does JIC mean in hydraulic fittings?

JIC is a thread type. A form of metal-to-metal sealing. Suitable for hydraulic systems.

How to measure JIC hydraulic fittings?

First measure the thread using a thread gauge. Only if the JIC thread gauge fits tightly into the fitting you have in your hand will this indicate a JIC thread.

Use calipers to measure the inner and outer diameter of the threads. You can check Topa’s datasheet for fit measurements.

What is the difference between JIC and SAE hydraulic fittings?

SAE hydraulic fittings are always used in those low pressure applications,like refrigeration etc.
JIC hydraulic fittings are invariably used in where high stress are involved,like fluid power.

Is JIC and NPT hydraulic fittings the same?

JIC hydraulic fittings are compression fittings ,having a 74 degree cone and parallel threads. NPT is a kind of United States standard tapered threads , providing an effective seal for piping .

JIC hydraulic fittings have better sealing power which can work under higher pressures. NPT threads are always used in those lower stress systems and are often used in conntecting ports.

What is the standard of JIC hydraulic fitting?

JIC hydraulic fitting was defined by SAE J514 and MIL-DTL-18866 those two distinct stangards ,and its flare seat is 37°. JIC hydraulic fitting is broadly used on those products with pressures up to 10,000 psi.

Should you use thread sealant on hydraulic fittings?

Some thread sealants are suitable for high-pressure hydraulic fittings. Fits any size NPT, O-ring boss or JIC fitting and resists rotation and leakage.

Can JIC hydraulic fittings be used on hydraulics?

JIC fittings are ideal for hydraulic applications. Widely used in the market. Metal-to-metal seal for high and low temperature fluids.

What is the difference between AN and JIC hydraulic fittings?

AN hydraulic fittings use threads with increased root radius ,and their tolerances are tighter. They are commonly used in US military aerospace applications.

The cone of JIC hydraulic fittings are 37 degree, and their thread quality are slightly lower than those of AN fittings, which are often used in those heavy machinery applications ,such as agricultural equipment and construction equipment.

What is the difference between JIC and JIS hydraulic fittings?

JIS hydraulic fittings are mostly used in Japan and South Korea for heavy applications, and their female cone seat are 60 degree . JIC hydraulic fittings are mostly perfered by the North American market, even popular in the whole world,and their female cone seat are 74 °.
