What does JIC mean in 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.

What are hydraulic fittings?

Hydraulic Fittings are used to connect a hydraulic hose to components like hydraulic cylinders, pipes, tubes, or different types of hydraulic hoses. The different types of hydraulic fittings allow the fluid to flow, change its direction, divert, or mix.

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.

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.

How do I know if my hydraulic fittings are JIC?

Four steps to know if your fittings are JIC:

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

Is JIC better than NPT?

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 JIS and JIC?

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.

What is the difference between SAE and JIC?

JIC fittings are dimensionally 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, and 10 share the same thread size.

How do you identify an fitting?

You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).

What is the difference between NPT and SAE?

What's the difference between SAE & NPT threads? The biggest difference is SAE is a straight thread, it needs additional O-ring, gasket or sealing surface to form a seal; NPT thread is a taper thread, it can form a seal using its thread pitch.

What is SAE hydraulic fittings?

SAE(SAE J512)stands for the Society of Automotive Engineers. SAE fittings are mostly used in refrigeration, automotive piping systems and other low-pressure applications. It's common for copper tubes to be used with SAE threads. SAE Flare The SAE male and female halves both have a 45° flare seat.

Is JIS the same as BSP?

JIS tapered thread connections are interchangeable with BSPT connections. connections are interchangeable with BSPP connections.

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.

Is UNF and JIC the same?

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).

What is JIC stand for?

JIC means “just in case.” It's commonly used to share a piece of information or convince someone of an action that probably won't be necessary but might be.

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.

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.

Are flare and JIC fittings the same?

AN and JIC Fittings Interchangeability AN 37° flare and industrial 37° flare fittings function identically. In many cases, they appear to be functionally interchangeable, but they are not.

What does BSP stand for in hydraulic fittings?

British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread.
