SAE 37 Degrees Flare Fittings

Flared Tube Fittings

The OmegaOne TX series fitting is a 37° Stainless Steel Flare Fittings or JIC (Joint Industry Council) fitting. The SAE 37° flare fitting is among the most reliable and durable fittings made making it the most popular type of tube fitting in North America. Defined by Joint Industry Council (JIC), the SAE 37° flare fitting is commonly referred to as the JIC fitting. The SAE flare fitting is defined by SAE specification J514 which supersedes MIL-F-18866 another commonly referenced standard for tube fittings.

The flare fitting involves three components, a fitting body, a flare sleeve, and a flare nut. The tubing used with flare fittings is seamless DOM (Drawn-Over-Mandrel) tubing. Welded tubing cannot be used to contain the pressures used commonly used in tube systems. A flaring tube is done either by hand with a flaring tool or more commonly a tube flaring machine. TX fittings are sold body only, TX nuts (TX-N) and sleeves (TX-S) are available independently or as part of a complete assembly. All TX series Flare Fittings are manufactured from 316 Stainless Steel.

The tubing is flared to accept the 37° flare nose of the fitting, the tube is flared to approximately 74°. When the nut is tightened it forces the sleeve and the tube together forming a metal-to-metal seal. The metal-to-metal seal is very tolerant to minor surface imperfections making the fitting durable. Flare fittings are tolerant of variations in hydraulic systems making them easy to install, service, and reuse. Re-assembly of a flare fitting does not require that any components be replaced.

The SAE 37 ° flare fitting is most commonly used to connect tubes or hoses in high-pressure and or high-temperature applications. The stainless JIC flare fitting is very tolerant to extreme high and low temperatures or thermal shock.
