This Legris 0127 series brass tube support is a metric brass tube fitting that connects to tubing. The brass tube support fits inside Legris compression fittings and thermocomposite tubing and is designed to avoid tube deformities at high temperatures and pressures. It presses against the inside of compression tubing. This brass tube support is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel.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.Parker Hannifin manufactures electromechanical, hydraulic, and pneumatic motion technologies and systems for fluid handling, filtration, sealing and shielding, climate control, process control, and aerospace applications. The company, founded in 1918, is headquartered in Cleveland, OH.
