SMC KQ2H03-34AS Brass Push-to-Connect Tube Fitting with Sealant, Adapter, 5/32" Tube OD x 1/8" NPT Male
This SMC KQ2H male adapter (also called connector) is a brass tube fitting for connecting a tube to a female thread. It has a push-to-connect inch tube connection on one end and male National Pipe Thread Taper (NPT) threads with fluororesin sealant on the other end. The body and threads are made of Japanese Industrial Standard (JIS) C3604 brass for corrosion resistance, and the tube seal is made of nitrile butadiene rubber (NBR) for resistance to oils and extreme temperatures. A chuck and collet provide secure retention of tubing, and the release button allows tubing to be removed with little force. The fitting can be used with nylon, soft nylon, polyurethane, fluorinated ethylene propylene (FEP), and perfluoroalkoxy (PFA) tubing. It has an operating pressure range of -14.5 to 145 pounds per square inch (psi) (-100 kPa to 1 MPa), an ambient temperature range of 23 to 140 degrees F (-5 to 60 degrees C), and a fluid temperature range of 32 to 104 degrees F (0 to 40 degrees C). This brass tube fitting is Restriction of Hazardous Substances (RoHS) compliant, and can be used in a broad range of fluid power applications, including temperature control, compressed air equipment, medical instrumentation, and motor vehicle controls, among others.

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, polybutylene terephthalate (PBT), 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.
