ABSTRACT:
A coupling for joining first and second channels in fluid communication includes a tubular housing having a first section including a wear surface, and a second section for being removably joined in fluid communication with the second channel. A first fitting includes a flange for being joined in fluid communication with the first channel, and an integral piston including a piston ring disposed in contact with the wear surface for forming a seal therewith. Differential movement between the housing and the piston is accommodated while maintaining a seal with the piston ring.
