JIC Fittings 

JIC hydraulic fittings are a type of hydraulic fitting that use a 37-degree flare seating surface to create a metal-to-metal seal between the fitting and the hydraulic tubing. JIC stands for "Joint Industry Council," which is a group that established standards for hydraulic fittings in the mid-20th century. JIC hydraulic fittings are popular in hydraulic systems because they provide a reliable and leak-free connection that can withstand high pressure and vibration. They are commonly used in industrial, automotive, and aerospace applications. JIC hydraulic fittings come in different sizes and configurations to accommodate different tubing sizes and thread types. They can be made of various materials, including stainless steel, brass, and carbon steel, to suit different operating environments. It is important to select the correct size and type of JIC fitting for your application to ensure a proper seal and prevent leaks or other issues.
