Abstract

A pipe coupling comprises a body part (1) having a hollow interior (4), a clamp nut (30) also having a hollow interior (32) and a die ring (20). The clamp nut (30) is threaded coaxially onto the body part (1) of the coupling and has a tapered interior. The die ring (20) is positioned within the tapered portion of the clamp nut (30) and has a gripping interior surface (23) and is connected to the clamp nut (30) so that the die ring (20) will rotate with the clamp nut (30). A pipe end (40) is inserted through the clamp nut (30) and the die ring (20) within the clamp nut (30), and into the body part (1) of the coupling. Rotation of the clamp nut (30) advances the clamp nut (30) onto the body part (1) and rotates the die ring (20) to force the threaded interior (23) of the die ring (20) into contact with the exterior wall of the pipe (40) to secure the pipe end in the coupling.
