What is a JIC female fitting?

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. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.

What threads do JIC fittings use?

JIC – Joint Industry Council Thread – SAE JIC 37° Commonly referred to as just JIC fittings these metal to metal sealing type fittings have a 37° flare (sealing surface angle) and straight United National Fine straight Threads (UNF).

Are JIC and an fittings compatible?

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

Are JIC and SAE fittings the same?

In some ways,JIC fittings are identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.

What size thread is JIC?

JIC 37° Flare (SAE J514)

Inch size	Dash size	Female thread O.D (in)
1⁄4	-4	13⁄32
5⁄16	-5	15⁄32
3⁄8	-6	17⁄32
1⁄2	-8	11⁄16

How do I stop my JIC fitting 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.

Should I use thread sealant on hydraulic fittings?

It works on any Loctite 5452 thread sealant is for use on high-pressure hydraulic and pneumatic metal fittings. It cures four times faster than anaerobic sealants on stainless steel or inert metals. It works on any size NPT, O-ring boss, or JIC fitting, and prevents rotation and leakage.
