Abstract
A flowline selector device has a housing with a single passage at the upper end and two or more passages at the lower end. A tube connects to the upper end and has a lower end that is offset from the axis of the housing. Reciprocating the tube up and down and rotating it causes the tube to index between the various ports in the lower end of the housing. The lower end of the tube stabs into cylindrical bores in each port. A piston located at the upper end of the tube cooperates with an orientation sleeve to cause the indexing and reciprocating movement.
