Epoxy Grooved Coupling is a pipeline connection device that simplifies installation and maintenance. It typically consists of three components: a sealing rubber ring, a clamp, and locking bolts.
The working principle involves placing the rubber seal into the pre-formed groove on the pipe exterior, securing it with the clamp, and tightening the bolts to achieve a leak-proof connection
