Understanding JIC Fittings: Your Complete Guide to the Size Chart

If you're in the hydraulic or pneumatic systems business, knowing the right fittings is crucial. JIC (Joint Industrial Council) fittings are a popular choice for those in need of reliable, leak-proof connections. In this article, we'll delve into the JIC fittings size chart and provide you with a thorough understanding of what you need to know.

What are JIC Fittings?

JIC fittings are a type of hydraulic fitting used to connect tubing and hoses in various systems. They feature a 37-degree flare design that ensures a tight seal when coupled with metal tubes. This design is especially beneficial in high-pressure applications, making them a staple in many industrial settings.

Why Use JIC Fittings?

• Versatility: JIC fittings can be used in a wide range of applications, including automotive, aerospace, and industrial machinery.
• High-Pressure Ratings: These fittings are designed to withstand significant pressure and temperature fluctuations.
• Durability: Made from high-quality materials such as stainless steel and brass, JIC fittings are built to last.
• Easy Installation: The 37-degree flare allows for simple assembly and disassembly, reducing maintenance time.
