JIC Hydraulic Fittings: Everything You Need to Know

JIC Hydraulic Fittings: Everything You Need to Know

Among the many hydraulic fittings available, JIC (Joint Industry Council) fittings stand out for their robustness, versatility, and reliability. One challenge in selecting the suitable fitting for fuel and hydraulic systems is the lack of a universal standard, which can vary by geographical location.

Understanding the differences between these and other standards when purchasing fittings for hydraulic assemblies is crucial, as each is manufactured to specific dimensions and tolerances. This knowledge will provide peace of mind and help you select the right fit for your application. 

Learn and select the correct standard to avoid loose connections, which can lead to leaks and hydraulic failures in your lines or hoses.

What are JIC Hydraulic Fittings?

What are JIC Hydraulic Fittings?
JIC (Joint Industry Council) fittings, defined by SAE J514, are compression fittings with a 37-degree flare seating surface and parallel threads. They are typically made from nickel alloys, brass, carbon steel, and stainless steel and are widely used in fluid power systems.

These fittings, known globally as "JIC" fittings, gained recognition and prestige through their association with SAE standards.

In 1950, the Joint Industry Council (JIC) decided to develop a standard for these fittings with the help of engineers from the Society for Automotive Engineers (SAE). They standardized the "AN" design but modified it to use the 2A/2B thread class for easier manufacturing.
