This PT Coupling white food-grade polypropylene safety bump plug provides an alternative to traditional cam and groove plugs. A large handle on the plug makes it easy to use, and the fitting is made of food-grade polypropylene for resisting most chemicals, excellent shape retention, sterilizability, and preventing the leaching of chemicals into materials that it comes in contact with. This cam and groove plug is an accessory to cam and groove hose fittings, which join hoses and pipes together in a variety of applications in the construction, mining, agriculture, manufacturing, automotive, and petroleum industries, among others.

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.
