What is JIC thread form?

What is JIC thread form?

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. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.

What thread is a JIC fitting?

JIC 37° Flare (SAE J514)

What is the difference between JIC and NPT?

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 JIC and SAE fittings?

The most common flare fitting standards in use today are the 45° SAE style, and the 37° AN style, also used with the JIC system. The AN / JIC style generally has a higher pressure rating for a given size tubing. SAE and AN/JIC fittings are completely incompatible due to the different flare angle.

What is JIC electrical standard?

These graphic symbols are the ones used most often on ladder diagrams for fluid power electrical control circuits. They are standard JIC (Joint Industrial Council) symbols as approved and adopted by the NMTBA (National Machine Tool Builders Association). Remember that JIC Standards are advisory only.

What is JIC 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 size is hydraulic?

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.

What is JIC and IEC?

JIC is an old standard that was replaced by NFPA. IEC is an International standard, a predecessor of the IEC standard. Many North American companies will accept equipment designed according to the IEC standard, but it sounds like your customer wants you to adhere to the UL-508A standard.

Which is a JIC thread and which is an AN thread?

JIC or AN union is simply a UNF thread with a convex (protruding) seat on the male and a concave (going inward) seat on the female. The JIC or AN seat is 74º when measured across them both. (If you have a UNF thread with 90º across the seat this is an SAE union – these are rare in automotive

What’s the difference between an and JIC fittings?

Each AN size also uses its own standard thread size. AN fittings are a flare fitting, using 37° flared tubing to form a metal-metal seal. They are similar to other 37° flared fittings, such as JIC, which is their industrial variant.

Are there JIC fittings for 45 degree flares?

SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size. Some couplings may have dual machined seats for both 37-degree and 45-degree flare seats. Komatsu and JIS (Japanese Industrial Standard) fittings have flare ends similar to JIC fittings.

Where did the idea of a thread come from?

AN thread. The AN thread is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army and Navy, hence AN.
