ABSTRACT:
The present retainer cap and valve protector fits over the valve head on a diver's oxygen tank to retain in place the usual O-ring which provides a fluid-tight seal between the valve head and an outlet flow regulator releasably attached to it. The retainer cap has a flexible, resilient, annular lip which springs back across the O-ring groove in the valve head to hold the O-ring in place when the outlet flow regulator is detached.
