This Colder NS6D13008 in-line tube coupling is made of polypropylene for resistance to chemicals, abrasion and corrosion. It has a 3/8" compression connection on one end and a 3/8" tube outside diameter (OD) connection on the other, and a shutoff valve for preventing spills. This coupling has a temperature range of 32 to 160 degrees F (0 to 71 degrees C), and supports working pressure to 120 psi (8.3 bar).
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.
Colder Products Company manufactures quick-connect couplings, fittings, and connectors for plastic tubing. The company, founded in 1978, is headquartered in St. Paul, MN.
