Jic fitting sizes

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

What size is #4 JIC fitting?

Inch size	Dash size	Male Thread O.D. (in)
¹⁄₈	-2	0.31
³⁄₁₆	-3	0.38
¹⁄₄	-4	0.44
⁵⁄₁₆	-5	0.50

What does JIC fittings stand for?

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.

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 threads are on a JIC fitting?

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).

Are JIC fittings the same as an fittings?

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

Does JIC fit NPT?

NPT fittingsis national pipe taper thread, They are available in low-pressure black iron and brass, and high-pressure steel and stainless steel. This connection style is used in pneumatic and process systems and hydraulic systems. JIC fittings is absolute different seal, not interchangeable.

Are JIC and SAE fittings the same?

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.

How do you determine thread size?

Use a pitch gauge. And check the thread against each form until you find a match. Some fractional

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 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.

Should you use Teflon tape on hydraulic fittings?

No. Teflon tape is for thread sealing. Hydraulic fittings are not sealed in the thread. They are sealed by O-ring or ferrule compression, neither of which requires teflon tape.

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.

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.

Can JIC fittings be reused?

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.

Is JIC tapered?

Flare. Both NPT and JIC fittings are machined with tapered ends.

Is UNF the same as JIC?

JIC / SAE 37 degree / UNF Straight. 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.

How do you identify hydraulic threads?

Four Steps to Thread Identification

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

What are an fitting sizes?

AN fittings range in size from -2 (dash two) to -32 in irregular steps that each equates to the outer diameter of the tubing. The outer diameter of the tube or hose that each fitting is to be used for is correlated with the inner diameter of the fitting itself.

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.
