Abstract

A cap assembly for closing an access opening in a plumbing fitting includes a cap for rotatable attachment to the plumbing fitting, with the cap having an interior surface which faces the plumbing fitting. There is an elastomeric friction ring positioned between the cap interior surface and the plumbing fitting, which friction ring has a plurality of circumferentially spaced projections facing and in contact with the plumbing fitting. The projections are formed and adapted to require less torque when the cap is rotatably attached to the plumbing fitting than when said cap is rotatably removed from the plumbing fitting.
