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