This Anderson Metals long flare nut compression tube fitting is made of brass, connects to a flared tube or fitting, 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 connects to a flared tube or fitting and can be used with copper, brass, aluminum, or steel tubing. It is part of an assembly that resists mechanical pullout for a more secure connection and can be assembled and reassembled without affecting the seal. This long flare nut compression tube fitting has an operating temperature range of -65 to +250 degrees F and 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. 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.Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.
