Abstract

A compression coupling assembly for joining at least one conduit. The compression coupling assembly includes a coupling body and a compression nut. The coupling body has an end portion and a central portion. The end portion has a threaded portion on an outer surface of the coupling body. The coupling body includes a plurality of spaced-apart teeth extending away from the threaded portion and the central portion. The compression nut includes an inner thread and a protrusion. The inner thread is configured to engage with the threaded portion of the coupling body. The protrusion has a leading surface that is configured to engage with the plurality of spaced-apart teeth. The plurality of spaced-apart teeth is configured to compress an outer surface of a conduit.
