Abstract
A valve includes a molded plastic body portion having an internal chamber forming a valve seat having inlet and outlet openings. A plastic plug member is rotatably positioned in the valve seat and has a flow passage which in the open position of the valve communicates with the inlet and outlet openings. Pipe fittings of the valve body communicate with the valve seat and are aligned with the inlet and outlet openings. Each fitting is coupled to a conduit of a piping system by a nut threaded into the respective fitting to urge a wedge-shaped collar into frictional engagement with the conduit. The nut surrounds the collar which is advanced by the nut into the fitting until a radial shoulder on the nut abuts the end of the fitting so that the end of the nut in the fitting applies a controlled compressive force upon a gasket seal to effect a fluid tight connection of the conduit to the fitting.
