This Eaton Weatherhead 1342 brass bulkhead fitting is suitable for connecting copper air brake lines through a bulkhead. The bulkhead fitting has 1/2" National Pipe Taper (NPT) male ends with an internal 1/4" NPT female connection. A washer and nut create an air-tight seal with the bulkhead. 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 fitting 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.
