This Dixon 2501 Series steel hydraulic fitting is a 90-degree elbow, or "ell," for connecting a hose to pump at a 90-degree angle to change the direction of flow, with a JIC 37-degree male flare on one end and male NPTF threads on the other end for connecting two female threaded ends. It is made of steel for tensile strength and hardness and coated with zinc for resistance to corrosion. This hydraulic elbow is suitable for use in low, medium, and high pressure hydraulic applications, such as automotive, agriculture, airline, as well as municipal and industrial applications, among others.

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.
