Eaton Weatherhead 1873X4X4 Brass CA360 D O T Air Brake Tube Fitting Female Bulkhead Union 1 4 NPT Female x 1 4 Tube OD

This Eaton Weatherhead 1873X4X4 brass bulkhead union with internal O-ring is a push-to-connect-type fitting for joining a 1/4" National Pipe Taper (NPT) female connector to 1/4" OD nylon tubing through a bulkhead. A female push-to-connect-type mechanism with O-ring fits over 1/4" outside diameter (OD) nylon tubing and the O-ring forms an air tight seal. The fitting is made of CA360 brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. It has a working pressure of up to 150 pounds per square inch (psi). This bulkhead union fitting meets U.S. Department Of Transportation (D.O.T.) FMVSS 571.106 air brake specifications and is suitable for use in air brake lines, such as those in buses and trucks. 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. Eaton manufactures electrical, hydraulic, and mechanical power equipment. The company, founded in 1911, is headquartered in Dublin, Ireland.
