A grooved pipe joint is comprised of four elements: the grooved pipe, the gasket, the coupling housing, and the nuts and bolts. The groove is made by cold forming or machining a groove into the pipe ends. A gasket encompassed by the coupling housing forms a seal on the two pipe ends, and the key sections of the coupling housing engage the grooves. The bolts and nuts are tightened with a socket wrench or impact wrench. In the installed state, the coupling housing encases the gasket and engages the grooves around the circumference of the pipe to create a leak-tight seal in a self-restrained pipe joint. There are two basic coupling styles that can be used on grooved pipe: flexible and rigid.
