Different Types Of Hydraulic Fittings - What Is An Orb Fitting?

What are ORB Fittings? ORB, or (SAE Straight Thread O-ring Boss) fittings, incorporate a port connection as recommended by the National Fire Protection Association (N.F.P.A.) for leak prevention in medium and high pressure hydraulic systems.

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.

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.

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.

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.

How is JIC fitting size measured?

Measure the thread diameter with an I.D./O.D. caliper. … Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections. Place the gauge on the threads until the fit is snug.

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.

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 does SAE stand for threads?

Society of Automotive Engineers (SAE) Threads These fittings are commonly used in refrigeration, automative and low presure applications. SAE 45° SAE J512. SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve.

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.

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.

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.

What is SAE J514?

Using the example in Figure 1, SAE J514 is a specific SAE standard that covers 37 degree flare and 24 degree flareless fittings, as well as pipe fittings and adapters. Another example of an SAE standard that could be used is SAE J1453, which is used for o-ring face seal fittings.

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 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.

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.

How are hydraulic fittings size?

Simply put, a dash size refers to an I.D. of a hydraulic hose or fitting in 1/16" increments. For example, -6 hose would indicate a hose with I.D. of 6/16" - or 3/8". Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter.

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.

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.

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.
