Victaulic Couplings use grooved pipe joining technology to connect pipes of various materials quickly and safely. A groove is formed or machined on the pipe end with a grooving tool and the housing is assembled around the grooved pipe ends. A gasket around the pipe creates a leak-tight seal while fasteners tighten the coupling.

Pipe grooves are created either through cut grooving, done by removing material from the outside diameter of the pipe, or roll grooving, a newer method which involves pressing a groove into the pipe wall.

Grooved couplings are either flexible, to enable controlled linear and angular movement, or rigid, to prevent movement like a flanged or welded joint.

Victaulic’s grooved pipe joining technology creates secure and reliable joint unions. It isolates vibration at each joint to reduce overall noise and vibration. The couplings are also quick to assemble and disassemble to save time on pipeline installation and maintenance.
