A grooved coupling consists of either a hinged body or two separate upper and lower body parts with an elastomer seal ring sitting inside. The joint is made when the coupling body and seal engages with groove profiles on the two sections of tubes being joined together.  Bolts on the coupling are then tightened so that the body and seal compress into the groove recess and the seal mating face. The combined force of the bolts, body and the seal rings being compressed around the tube makes the joint.

Grooved couplings are easy to fit and provide a quick and easy, heat-free and demountable joining system.  They must be used with grooved tubes; these are tubes that have a rolled or cut grooved profile of specific dimensions around the circumference of the tube end.  Different elastomer seal materials may be used for different applications.

Typically these couplings are manufactured from ductile iron or stainless steel and are supplied with a galvanised or painted finish dependent upon the application.
