When To Use Flared Tube Fittings

Hy-Lok Canada has remained the top manufacturer and supplier of fluid system fittings and valves in Canada since 1977. With our robust fittings inventory and a nationwide network of distributors, Hy-Lok carries fitting your fluid system needs for optimum performance.

Fittings are a vital part of the CNG (Compressed Natural Gas Market), oil & gas, chemical and instrumentation industry. Certain connections are used in the field to ensure smooth production while withstanding high pressure and temperature ratings. Some may require flared fittings depending on the application used, while others can use regular flareless fittings. Wondering which fitting your connection requires? Read on to learn more!

What are Flared Tube Fittings?

Flared tube fittings are connections that have tapered ends which fit into flared tubes and are secured in place using the sleeve and flare fittings. Flared fittings are primarily used in applications that undergo severe vibrations, pressure bursts, and thermal shocks as the sleeve and flare fittings produce a pressure-resistant, leak-tight seal. Compared to pipe fittings, flared fittings are designed to provide significant performance characteristics.

Which Industries Require Flared Tube Fittings?

Pipe fittings have been long replaced with flared fittings, particularly in most hydraulic, military and aerospace equipment. They are also suitable for plumbing and heating in industries like gas, oil, air and water. Industries that use heavy machinery and industrial and construction equipment require flared tube fittings as they can securely connect tubes or hoses in high pressure and temperature applications.

Hy-Lok’s 37º Flared JIC Tube Fitting

The most common flared tube fitting is the SAE 37º Flare JIC, as it can seamlessly connect to thin and medium diameter wall tubing. It is designed with three main components: the body, the ferrule and the nut. All three parts work together to create a tight metal-to-metal seal to ensure that the tubing does not undergo distortion and remains constant under extreme conditions. Manufactured from top-quality stainless steel, Hy-Lok’s flared tube fittings are also available in brass, aluminum and carbon steel upon request.

Our 37º flared JIC fittings are popular among heavy industries as they are fully compatible with ORB, SAE and JIC standards. We offer a comprehensive range of sizes and specifications of flared fittings that can be integrated seamlessly with vehicles, hydraulic ramp systems, brake lines etc. With Hy-Lok’s fittings, you will no longer worry about running out of stock or having to run a special order; all our fittings are designed to be 100% interchangeable with Swagelok, Parker, and other manufacturers’ components – you can easily integrate our products into your existing fluid system.
