Abstract
A variable length coupling device for connecting together first and second flowlines for the passage of fluid therethrough including first and second housing sections having alignable bores. The first housing section is adapted for connection at various angular positions to the first flowline and the second housing section to receive and is sealingly attached to the second flowline in response to the interconnection of the first and second housing sections. An actuator sleeve, force transfer sleeve and wedging seal ring are mounted within the first and second housing section bores for movement into gripping, sealing engagement against the second flowline in response to connection of the first and second housing sections together. In a further embodiment, a third housing section is interposed between the first and second housing sections and the actuator sleeve, force transfer sleeve and a seal ring mounted therein for movement into gripping, sealing engagement against the second flowline in response to connection of the first and second housing sections to the third housing section.
