JIC Fitting is a range of hydraulic fittings which is made in accordance with SAE J514 and ISO 8434-2 standards. The acronym JIC stands for Joint Industry Council, 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.
DIFFERENCE IN STANDARDS
The commonality between all these fittings is that they define how a component joins and seals to other hydraulic components like their female counterparts, pipes, hoses, and valve blocks. The sealing mechanism depends on the metal-to-metal contact achieved when two compatible fittings are linked.
Each standard is defined by the internal diameter, thread sizing dimensions of the adapter, the flare angle on their nose, and whether the threads run parallel or taper.
AN VS JIC:
The only difference between AN and JIC fittings is that AN fittings are manufactured as per more stringent tolerances for military applications.
JIS AND KOMATSU VS JIC:
JIS and Komatsu are similar in their appearance to JIC fittings; however, they have a 30° flare on their fittings as opposed to the 37° flare in JIC fittings. Additionally, JIS conforms to the BSP (British Standard Pipe) thread sizing and Komatsu to the millimeter.
SAE VS JIC:
The thread sizing in JIC fittings are based on SAE parallel running thread sizing. It is for this reason why SAE 45° flare thread fittings can thread onto JIC fittings; however, caution must be taken as they do not have the same flare angle for seating.
