This Anderson Metals half union compression tube fitting (#54048-0604) is made of brass, has a flared tube connection and a male NPT connection, and is suitable for use with fuel and gas systems. It is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. This fitting can be used with copper, brass, aluminum, or steel tubing to connect and disconnect two tubes more easily than with a coupling. It has a flared tube connection on one end and a male National Pipe Taper (NPT) connection on the other for connecting to a female NPT threaded tube, creating a tighter seal than straight threads. Also, the assembly resists mechanical pull-out for a secure connection, and can be assembled and reassembled without affecting the seal. This reducing union compression tube fitting has an operating temperature range of -65 to +250 degrees F and therefore is suitable for use with fuel and gas systems, plumbing, refrigeration, and vacuum applications.

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. Machine tools, airplane and truck controls, and automated production lines (among others) use tube fittings in various applications. These fittings contain lead and are not allowed by federal law to be installed for potable water use in the U.S.A. and its territories.

Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.
