ABSTRACT:
A fluid quick connector includes first and second coupled housings having aligned bores. A biased shut off valve is mounted in the first housing and has a seal end normally biased into a fluid flow blocking position; but movable away from the seal upon contact with an end form inserted into the bores to a fluid flow enabling position. The first and second housings interact at an adjustable axial interface formed of mating threads to vary the insertion distance of the endform into the first housing after the endform is latched in the first and second housings by a retainer carried in the second housing, to regulate the fluid flow through the quick connector.
