What is a grooved coupling?

Long and narrow indentation in a part/material, usually for other parts to fit into

In manufacturing or mechanical engineering a groove is a long and narrow indentation built into a material, generally for the purpose of allowing another material or part to move within the groove and be guided by it. Examples include:

1. A canal cut in a hard material, usually metal. This canal can be round, oval or an arc in order to receive another component such as a boss, a tongue or a gasket. It can also be on the circumference of a dowel, a bolt, an axle or on the outside or inside of a tube or pipe etc. This canal may receive a circlip, an o-ring, or a gasket.
2. A depression on the entire circumference of a cast or machined wheel, a pulley or sheave. This depression may receive a cable, a rope or a belt.
3. A longitudinal channel formed in a hot rolled rail profile such as a grooved rail. This groove is for the flange on a train wheel.

Grooves were used by ancient Roman engineers to survey land.[1]

Today grooved couplings along with grooved fittings, grooved valves and grooved accessories (such as strainers and suction diffusers) are found in a seemingly endless number of piping applications worldwide.

While the grooved pipe joining concept has become synonymous with faster and easier installations, not all manufacturers of grooved products are the same. We are unique. There is only one Victaulic for reliable, durable, precision-constructed piping systems.
