Y Hydraulic Fittings - What Does JIC Stand For Fitting?

What are JIC 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.

What are the 5 common types of fittings?

Different pipe fittings and their functions are explained below.

• Elbow.
• Reducer.
• Tee type.
• Cross type.
• Coupling.
• Unions.
• Adaptors.
• Olet.

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).

Are brass fittings OK for hydraulics?

Although not one of the most common fittings used in fluid power applications, brass fittings are extremely useful in corrosive environments for both hydraulic and pneumatic hose and tubing applications.

What are the 4 types of fittings?

Coupling, Adapter, Bushing and Union Fittings For example, an adapter could be fitted on the end of a plain pipe to allow a threaded connection at the other side of the adapter. Bushing Fittings - Bushings, sometimes called reducer bushings, are used for connecting two pipes of different sizes.

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.

Will JIC seal on SAE?

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 JIC stand for hydraulic?

JIC 37⁰ Flares: The Joint Industrial Conference (JIC) fitting is the most common hydraulic connection style. It consists of parallel threads and a 37⁰ cone on the fitting end that attaches to either a flared tube or hose fitting.

How do you identify hydraulic fittings?

Four Steps to Thread Identification

1. Step 1 – Determine if the thread is tapered or parallel. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel.
2. Step 2 – Determine the pitch.
3. Step 3 – Determine the size.
4. Step 4 – Designate the thread.

What is the most common fitting used?

A tee, the most common pipe fitting, combines or divides fluid flow. Tees can connect pipes of different diameters, change the direction of a pipe run, or both.

Is 37 flare the same as JIC?

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.

Can you reuse JIC fittings?

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.

Are JIC and SAE the same?

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 JIC and an fittings the same?

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

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.

How do you seal a JIC fitting?

Simple just push one onto the male side of a jic fitting. Or seat it in the female.

What are the three types of fittings?

The Three Types Of Fit

• Clearance Fit. Clearance fits allow for loose mating, where free movement is important and a certain amount of play is desired.
• Interference Fit. An interference fit will be much tighter than a clearance fit.
• Transition Fit. A transition fit would fall between a clearance and interference fit.

Is JIC 37 or 45?

The JIC female has straight threads and a 37° flare seat. The Seal is made on the 37° flare seat. The SAE 45° flare male will mate with an SAE 45° flare female only. The SAE male has straight threads and a 45° flare seat.

What are the most common hydraulic fittings?

The three most common fitting ends and connector types for hydraulic fittings are the O-ring, the mated angle, and the tapered thread connectors. Although these are the most popular choices, several other types are used in different and specialised applications.

What is the best type of hydraulic fitting?

To address high operating pressure, more and more of our customers prefer to use O-ring seals. They are more resistant to cracks. O-ring seals also prevent the risk of over-torqueing and leakage. In terms of material stainless steel hose fittings have the highest pressure rating.
