GripLock Connector

GripLock_PhotoThe Oil States Griplock™ Connector (GLC) is a mechanical pipe end connector used for pipeline repairs, reroutes and abandonment projects. The GLC utilizes collet grips that mechanically attach to a pipe and create a permanent, structural flanged end on the pipe.

The GripLock™ uses standard, dual-barrier Viton seals to deliver long-term integrity and comes equipped with a test port to verify the annulus seal. Fast, reliable “single-set” design actuates grips and seals simultaneously.
