This PT Coupling STA LOK II Type C reducer has an aluminum body, a buna-n (buna nitrile) gasket, and a hose shank end for adapting hose to a cam-locking male coupler of a different diameter. The aluminum reducer body is lightweight and provides corrosion and abrasion resistance and is suitable for use with water, hydraulic oil, coolants, gasoline, and petroleum products. The cam arms serve as the mechanism by which the coupler locks into the adapter groove. When the fitting is fully closed, an automatic locking system engages to help keep the cam arms from opening under adverse conditions such as high vibrations, pulsing, and hazardous materials. The buna-n seal provides a leak-tight connection and is suitable for use with the same materials as the aluminum body. This cam and groove adapter complies with Commercial Item Description A-A-59326D for quick disconnect fittings, meets the Coast Guard ASTM International (ASTM) standard 1122-87 for quick disconnect couplers, and is used in low-pressure applications such as fuel delivery, wine transfer, and grain movement.Hose fittings connect, control, change the direction of, and terminate the flow in piping and hose systems. They are made of brass, stainless steel, galvanized steel, and other materials that resist corrosion, pressure, and wear. Hose fittings have various types of connections, including threaded, barbed, push-to-connect, dry disconnect, and others including those based on internationally-accepted specifications. Hose fittings are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.PT Coupling manufactures pneumatic and hydraulic hose fittings for industrial and automotive applications. The company, founded in 1951 and headquartered in Enid, OK, meets International Organization for Standardization (ISO) standard 9001.
