Jic fitting

JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel.

Is JIC and NPT the same?

JIC fittings come with a 37O flare angle, while the NPT fittings rely on just their tapered threads for sealing. As a result, JIC fittings offer better sealing capabilities and can withstand higher working pressures.

What is the difference between JIC and SAE fittings?

The most common flare fitting standards in use today are the 45° SAE style, and the 37° AN style, also used with the JIC system. The AN / JIC style generally has a higher pressure rating for a given size tubing. SAE and AN/JIC fittings are completely incompatible due to the different flare angle.

Is JIC 37 same as an?

JIC Steps In The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.

Do JIC fittings need sealant?

Even though JIC threads seal with a metal-to-metal connection, no thread sealant is required to achieve a leak free connection.

Is JIC 37 or 45?

JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface.

Do JIC fittings need O rings?

Most commonly used as hydraulic fittings in the fluid power industry, JIC (Joint Industry Council) fittings are a type of flare fitting machined with straight threads using a 37° flare seating surface. This is used to form the seal of the fitting instead of an o-ring or tapered threads.

How do I identify my JIC fittings?

If you look at the inside of this female fitting. You will see there is a 37 degree flare at the

How do I know if my hydraulic fittings are JIC?

Four steps to know if your fittings are JIC:

Identify if the thread is parallel or tapered. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel.
Determine the flare angle by using a calipers.
Determine the thread diameter. ...
4.Identifying the thread by gauge.

Is JIC compatible with NPT?

NPT fittingsis national pipe taper thread, They are available in low-pressure black iron and brass, and high-pressure steel and stainless steel. This connection style is used in pneumatic and process systems and hydraulic systems. JIC fittings is absolute different seal, not interchangeable.

Are JIC fittings reusable?

Though industry generally accepts that JIC 37° flare fittings are reusable, they may not always be reliable when reused. In fact, the JIC 37° flare fitting tops the Most Questionable list for reassembly.

What thread size is JIC?

Inch size	Dash size	Female thread O.D (in)
¹⁄₂	-8	¹¹⁄₁₆
⁵⁄₈	-10	¹³⁄₁₆
³⁄₄	-12	1
⁷⁄₈	-14	1 ¹⁄₈

Should you use Teflon tape on hydraulic fittings?

No. Teflon tape is for thread sealing. Hydraulic fittings are not sealed in the thread. They are sealed by O-ring or ferrule compression, neither of which requires teflon tape.

How do I stop my JIC fittings from leaking?

But leaking flare joints can be eliminated by installing a conical washer between the JIC nose and flare. One type of flare seal, manufactured by Flaretite, consists of a stainless steel stamping, with concentric ribs that contain pre-applied sealant.

How tight should a JIC fitting be?

Thread the hose end or adapter nut onto the fitting until it cannot be tightened by hand any further. Lightly tighten the nut with a wrench (approximately 30 in. lbs.) making sure it does not bind; this is also known as tightening until wrench resistance.

How much pressure can a JIC fitting hold?

Pressure Ratings Working pressures up to 5000 PSI. Working pressures will vary depending on tube and fitting size. (For applications using extreme pressures at 5000 PSI or above, contact World Wide Fittings.)

Are brake lines 37 or 45 degree flares?

The 45-degree inverted flare is the most common style of flare used in automotive hard lines like brake, fuel, and transmission fluid transfer.

Will a 45 degree flare work on a 37 degree fitting?

JIC 37 degree flare union fittings is in most hydraulic systems in high pressure application such hydraulic excavator, loader and tractor etc. SAE 45 degree flare fittings is used in low to medium pressure applications such as military and aerospace equipment. they doesn't interchangeable into each other.

What does hydraulic JIC stand for?

What does JIC stand for? JIC stands for the Joint Industries Council, which first standardized industrial use fittings. These compression couplings have a 37° flared seat on the male and female threaded connections.

What is the difference between JIC and JIS?

Usage difference: JIS hydraulic fttings mainly used in Japanese and Korean heavy equipment such as Komatsu, Kobelco, Hitachi, Kubota etc, often used as hose adaptors. JIC hydraulic fittings mainly used in North America market, also popular in the worldwides.
