This Eaton Weatherhead C5165X12 steel reinforcement sleeve is suitable for use as part of a 3-piece 3/4″ tube outside diameter (OD) JIC 37-degree flare fitting assembly (not included). The sleeve fits over 3/4″ outside diameter (OD) copper, brass, steel, or aluminum tubing and compresses to form an air tight seal. The fitting has a working pressure of up to 2,500 pounds per square inch (psi), depending on the tubing material used. The fitting is made of carbon steel for durability and resistance to rupture under high pressure and is zinc plated for resistance to corrosion. This Joint Industry Council (JIC) 37-degree flare sleeve fitting meets the Society of Automotive Engineers (SAE) J514 standards for quality assurance and is suitable for use in hydraulic applications such as in hydraulic cylinder lines.

Tube fittings are components used for connecting, branching, terminating, and changing the direction of tubing in pneumatic and hydraulic systems. They are made of brass, stainless steel, polybutylene terephthalate (PBT), and other materials that resist corrosion and wear. Tube fittings have various types of connections, including threaded, welded, barbed, and push-to-connect (also called one-touch). Push-to-connect connections do not require tools or sealants. Tube fittings are used in various applications, including machine tools, airplane and truck controls, and automated production lines, among others.
