ABSTRACT:
A grip-seal apparatus for connecting together flowline end portions including first and second housings having alignable bores therethrough and an intermediate housing connection section for connection to each of the first and second housings and also having a bore for receiving a first flowline end portion. A radially contractable actuator sleeve is mounted within the bore of the first housing for movement radially inwardly into gripping engagement with the first flowline end portion in response to camming action; and, a sealing assembly is mounted in the bore of the second housing for movement radially inwardly into sealing engagement with the first flowline end portion in response to longitudinal movement of an activating sleeve which is mounted within the second housing bore in engagement with the sealing assembly. The second housing is connectable to various types of flanges for connection to another grip-seal apparatus attached to a second flowline end portion or for connection directly to the second flowline end portion whereby fluid flow between the first and second flowlines is established.
