Abstract

A compression ring includes an outer surface opposing an inner surface, with teeth extending radially inwardly from the inner surface. First and second circumferential ends are complementarily interfittable, and are separated by a circumferential gap, allowing the compression ring to be compressable when being installed in a connector assembly. First and second axial ends of the compression ring are chamfered to facilitate compression. The teeth extend circumferentially from the first and second circumferential ends and are complementary to conduit threading. Each tooth includes first and second sides, with the first side perpendicular to the inner surface to resist pullout of a conduit from the connector assembly. The teeth terminate in sharp points for better gripping of unthreaded conduits. A compressed compression ring accommodates threaded conduits by complementarily mating with threading, and unthreaded conduits by biting into their outer surfaces. Internal and external sealing gaskets provide seals from moisture.
