Section 3: Differences Between JIC and JIS Hydraulic Fittings
JIC (Joint Industry Council) and JIS (Japanese Industrial Standard) fittings are two different types of hydraulic fittings, each with its own unique characteristics and uses. Here are some of the key differences between these two types of fittings:
⦁ Flare Angle: The most significant difference between JIC and JIS fittings is the flare angle. JIC fittings have a 37-degree flare angle, while JIS fittings have a 30-degree flare angle. This difference in angle affects the way the fittings seal and connect to the hydraulic tubing or hose.
⦁ Thread Type: JIC fittings typically have Unified National Fine (UNF) threads, while JIS fittings have metric threads. This means that JIC fittings may require different tools and adapters than JIS fittings when installing or repairing hydraulic systems.
⦁ Standards: JIC fittings are governed by SAE (Society of Automotive Engineers) standards, while JIS fittings are governed by Japanese Industrial Standards. This means that the specifications and performance standards for JIC and JIS fittings may differ slightly.
