1. The Grooved Concept Instead of welding or threading, a groove is rolled or cut into the end of the pipe. A Grooved Coupling (containing a C-shaped gasket) is then bolted over the two pipe ends to create a seal. 2. Rigid vs. Flexible Couplings Rigid Couplings: Create a joint that behaves like a we …
