Reliable Grooved Rigid Couplings for High-Pressure Applications

Grooved Rigid Coupling

Grooved Rigid Coupling creates a firm joint by securely gripping the entire circumference of the pipe grooves. LAMINAR Grooved Rigid Couplings offer a reliable and cost-effective alternative to welding, threading, or flanges for joining pipes. They can handle pressures up to 34.5 Bar (500 psi), depending on pipe size and wall thickness, making them ideal for demanding application like fire protection services.

Grooved coupling includes housing, gasket and fasteners to create a groove leak-tight structure. Rigid grooved coupling offers rigidity through grip teeth in the housing, and it does not allow for movement, similar to a rigid flanged or welded joint.
