Abstract
A coupling arrangement for permitting fluid-tight, pressurized fluid flow therethrough includes a pair of conduit members located in end-to-end alignment, each of the conduit members having a flared end. An encircling coupling unit surrounds the ends of the conduit members and has structure to tighten the coupling unit around the flared ends of the conduit members, the coupling unit having inner lateral surfaces partially defining a coupling cavity. An encircling, deformable gasket is disposed in the cavity of the coupling unit. The gasket has exterior lateral surfaces spaced from the inner lateral surfaces of the coupling unit, and interior surfaces defining an annular recess therein. A rigid ring liner is retained within the annular recess of the deformable gasket to reinforce the gasket. The flared ends of the conduit members are engaged in wedging and sealing relationship between the inner lateral surfaces of the coupling unit and the exterior lateral surfaces of the deformable gasket.
