Flexible grooved couplings enable controlled movement at the pipe joint, allowing pipes to expand, contract, or deflect from the center line within limits. The system uses a rubber gasket stretched over grooved pipe ends, with coupling segments and bolts creating a leak-free connection. They reduce noise and vibration transmission between connected pipes.
