Flexible Rubber Coupling for Pipes
Flexible Rubber Coupling for Pipes is a mechanical coupling that allows the pipe to be deflected and connected to the spigot end of the pipe by tightening the rubber ring. The flexible connection allows for a small amount of displacement, deflection, contraction and expansion of the pipe.
