Abstract
A hydraulically actuated coupling for effecting a connection to a pipe member or the like which has axially spaced apart pluralities of oppositely biased gripping slips which are continuously urged into gripping engagement between the housing and the pipe. This arrangement permits the pipe coupling to withstand both tension and compression forces thereon and to continuously maintain slips in positive engagement with the pipe. The coupling also has separate seal means which are separately operated by a thrust member which applies axial force to thereby radially deform elastomeric seal members into sealing engagement between the pipe and the housing. The separate actuation means for the slips and for the seal means provides a more fail-safe coupling and one which can be adapted to various pipe sizes and pressure requirements.
