JIC (Joint Industry Council) hydraulic fittings are a flare fitting with a 37 degree flare seating surface and straight threads. They are used in high pressure fluid power applications because of the metal to metal seal. These fittings have three main components:the body, nut and sleeve. The seal is made by the male flare seating on the female coned seat to form a mechanical connection. JIC fittings are made from materials like carbon steel, stainless steel, brass and nickel alloys so they can be used in many industries like agriculture, chemical processing and aerospace.

China JIC Metal Fittings are precision-engineered to deliver superior performance in high-pressure hydraulic systems. Crafted from premium materials and designed in strict compliance with international JIC standards, these fittings ensure leak-free operation and robust reliability even under extreme conditions. Ideal for diverse applications—including industrial machinery, construction equipment, and automotive systems—they combine ease of installation with long-lasting durability, making them a trusted solution for professionals seeking excellence and innovation in hydraulic connectivity.

Backed by certifications such as ISO 9001 and IATF 16949, these hydraulic fittings showcase the competitive edge of China in global markets –combining cost efficiency with state-of-the-art precision engineering, and setting new benchmarks in the field of hydraulic components.
