Jic hydraulic fittings

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. JIC Fitting hydraulic connections are common in most fluid power systems.

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.

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.

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.

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.

What is JIC stand for?

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.

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.

Is JIC and NPT compatible?

JIC fittings is absolute different seal, not interchangeable. JIC hydraulic fittings is used in high pressure system, NPT fittings is used in low-pressure system. NPT pipe threads have always been popular, as leaks can be fixed by simply tightening the fitting.

How do I know my JIC fitting size?

You want to take your fitting. And you want to take your thread pitch gauge. You want to find number

Are SAE and JIC fittings interchangeable?

SAE and AN/JIC fittings are completely incompatible due to the different flare angle. Furthermore, AN fittings (or those complying with subsequent standards) and JIC fittings are not interchangeable for design-controlled applications due to differing quality standards.

Can you mix JIC and an fittings?

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

Why is it called JIC fitting?

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 BSP?

Thrust-wire fittings are either BSP (8,000 PSI proof pressure) or JIC (6,000 PSI proof pressure) and are specifically used in high-pressure, high-vibration applications.

What is JIS hydraulic fitting?

JIS fittings are typically used as hose adapters on equipment designed and/or manufactured in Japan and Korea. Parker's JIS adapters are designed with 30° flare and 60° cone connections and typically incorporate BSP threads.

Are JIC and UNF the same?

JIC Thread Identification 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).

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.

Is it OK to use Teflon tape on hydraulic fittings?

No. Teflon tape is for thread sealing. Hydraulic fittings are not sealed in the thread.

What size is JIC?

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

What are the different types of hydraulic fittings?

Types of hydraulic fittings vary depending on their sizes, configuration, and thread types. The three most common types of hose fittings are O-ring, mated angle and threaded.
