ABSTRACT A coupling for forming a sealed engagement with a tubular member, the coupling comprising an annular housing having an engagement zone for receiving a tubular member to be engaged by the coupling, and comprising an engage- ment assembly positioned within the engagement zone. The engagement assembly comprises an annular gasket for sealing engagement with a tubular member upon axial compression of the engagement assembly. The annular gasket has a plurality of circumferentially spaced bores. A plurality of bolts for axial compression of the engage- ment assembly, are positioned to extend through the bores. The engagement assembly includes at least one washer for applying axial pressure to the annular gasket during axial compression of the engagement assembly. The engagement assembly further includes a gripping ring to be radially compressed upon axial compression of the engagement assembly to grip a tubular member when positioned in the engagement zone. The engagement assembly further includes wedge surfaces to cooperate with the gripping ring to resiliently compress the gripping ring into engagement with a tubular member. An axial compression limiting member is provided in the form of a shoulder or flange, or separate spacing ring to limit the axial compression of the engagement assembly and thereby determine the ultimate degree of radial displacement of the gripping ring.
