ABSTRACT:
A grip-seal apparatus for connecting together flowline end portions having first and second housings having alignable bores therethrough, with gripper member mounted in the first housing for moving radially inwardly into gripping engagement with the first flowline member. A sealing assembly is mounted with the second housing for moving radially inwardly into sealing engagement with the first flowline member. An activating sleeve mounted in the second housing and with the gripper members moves longitudinally into engagement with the gripper members and the sealing assembly. Fasteners with the activating sleeve fasten the first and second housings therewith resulting in the longitudinal movement of the activating sleeve with respect to the gripper members and the sealing assembly, with such action resulting in the gripper members moving radially inwardly into a gripping engagement with the first flowline member and the sealing assembly moving radially inwardly into sealing engagement with the first flowline member. Connection members with the second housing connect the second housing with the second flowline member in order to reestablish fluid flow between the first and second flowline members.
