Jic meaning fittings

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's the difference between an and JIC fittings?

The Joint Industries Council (JIC), sought to clear the air by standardizing the specifications on this type of fitting by creating the "JIC" fitting standard, a 37-degree fitting with a slightly lower class of thread quality than the military AN version.

How do I know if I have a JIC fitting?

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.

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.

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.

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.

Is JIC 37 or 45?

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.

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.

How does a JIC fitting seal?

The seal in JIC fittings is created through the metal-to-metal contact of the finished surface of the fitting nose and the inside of the flared tubing. The fitting sleeve supports the connection between the fitting nose and the inside of the flared tubing by distributing the compression during assembly.

What size thread is JIC?

Inch size	Dash size	Female thread O.D (in)
¹⁄₂	-8	¹¹⁄₁₆
⁵⁄₈	-10	¹³⁄₁₆
³⁄₄	-12	1
⁷⁄₈	-14	1 ¹⁄₈

How do I know what type of hydraulic fittings I have?

There are six types of threads commonly used on hydraulic tube fittings: UN/UNF. NPT/NPTF. BSPP (BSP, Parallel) ... Four Steps to Thread Identification

Step 1 – Determine if the thread is tapered or parallel.
Step 2 – Determine the pitch. ...
Step 3 – Determine the size. ...
Step 4 – Designate the thread.

How do I know what size hydraulic fitting I need?

Measuring the Outer Diameter of the thread – place the ID/OD caliper around the threads so as to obtain a snug fit. Measuring the Inner Diameter of the thread – insert the caliper into the fitting so you can obtain the correct measurement, and match it to the data charts provided by the manufacturer.

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 the difference between 37 and 45 degree flare?

JIC 37 degree flare union fittings is in most hydraulic systems in high pressure application such hydraulic excavator, loader and tractor etc. SAE 45 degree flare fittings is used in low to medium pressure applications such as military and aerospace equipment. they doesn't interchangeable into each other.

What is 37 degree flare used for?

Defined by MIL-F-18866 and SAE J514 standards, these flare fittings have been machined to have a 37° flare seating surface. These fittings are most commonly used in fluid power and fuel delivery applications, especially those using high pressure.

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.

Is SAE the same as NPT?

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.

Is JIC and UNF the same?

The only effective difference is that JIC (also known as SAE 37 degree) has a conical seating face (37 degree or 74 degree total angle) and UNF Straight has a flat seat - sealing being effected by use of a washer. Male JIC fittings have a convex cone, female fittings a concave cone.

Is JIC pipe threaded?

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 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.
