Groove Couplings

Grip ring coupling (grip pipe coupling) is designed to conveniently join pipes together without the need of welding, grooving and threading of pipes. The grip ring coupling (grip pipe coupling) allows for the pipes to be securely fastened under pressure for a variety of situations and uses. It comes in a number of diameters and sizes for maximum versatility.
