ABSTRACT:
A conduit coupling for conduit sections includes a body with a rigid, outer casing and an elastomeric inner core. The core includes a passage with annular ridges for sealing the coupling on the conduit. A pair of lock nuts are mounted on the casing ends and each receives a gripper ring with gripper ring ridges for engaging the conduit. The lock nuts are threadably mounted on the casing for tightening the gripper rings against the conduit sections to resist pull-out.
