This Eaton Weatherhead C5205X4X4 adapter fitting is suitable for joining a pipe to tube in a range of fluid transfer applications. It has 1/4" male National Pipe Taper (NPT) threads on one end and male 7/16-20 Joint Industry Council (JIC) threads on the other for use with 1/4" outside diameter (OD) tubes. The fitting is made of zinc-plated 12L14 carbon steel for strength, durability, and resistance to corrosion, has an operating temperature range of -65 to +400 degrees F (-53 to +204 degrees C), and meets Society of Automotive Engineers (SAE) 070102 specifications for tube fittings. This adapter fitting is suitable for use in hydraulic, instrumentation, and chemical processing systems.

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, PBT (polybutylene terephthalate), 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.

Eaton manufactures electrical, hydraulic, and mechanical power equipment. The company, founded in 1911, is headquartered in Dublin, Ireland.
