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 metric tube connection on one end and male British Standard Pipe Taper (BSPT) 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.Specifications
