A grooved fitting, also known as a grooved coupling, has four elements: grooved pipe, gasket, coupling
housing, and nuts and bolts. The groove is made by cold-forming (or machining) a groove at the end of a
Grooved coupling pipe joining systems uses a roll grooving technique to join pipes and pipe joining
components. A groove is placed on the outside of the pipes near the ends to be joined.
We deliver quality grooved piping solutions for a full range of fire applications, which install faster and are
more cost-effective for joining pipe than traditional welding methods. Grooved couplings and fittings allow
installers to fabricate on-site and around complex obstacles. No special tools are needed, fire permits are not
required, nor do building residents have to evacuate due to welding fumes.
