ABSTRACT:
A bleed-down connector assembly is described which employs a rotatable cap for controlling the axial movement of the conduit in the connector housing between the sealed and bleed-down positions. The cap is mounted concentrically over the housing for both rotational and axial movement with respect to the connector housing. The cap includes a wall portion which is formed to engage a retainer associated with the connector assembly for retaining or maintaining the conduit in the housing. The housing is formed to provide a ramp of varying axial length and the cap is formed with a plurality of depending spring-like tabs which engage the ramp and limit the axial movement of the cap with respect to the housing.
