This Legris 0116 bulkhead union compression tube fitting is made of brass, has metric tube connections, and is suitable for high-temperature, pressure, and vacuum applications. This bulkhead union fitting connects two metric tubes, in a straight run, through a panel. It is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability, and has an operating pressure rating range of 200 to 500 pounds per square inch (psi) at a temperature range of -65 to +250 degrees F. This bulkhead union compression tube fitting meets the Restriction of Hazardous Substances Directive (RoHS), adopted by the European Union (EU), and is suitable for use in high-temperature, pressure 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. Parker Hannifin manufactures electromechanical, hydraulic, and pneumatic motion technologies and systems for liquid handling, filtration, sealing and shielding, climate control, process control, and aerospace applications. The company, founded in 1918, is headquartered in Cleveland, OH.
