ABSTRACT:
A safety cap for preventing unauthorized access to a refrigerant valve is described. The safety cap has a locking piece that attaches to the valve's threaded portion and covers the valve's access port. A collar surrounds the locking piece and is mechanically decoupled therefrom, so that motion is not communicated therebetween. The locking piece has a topographic feature such as a number of asymmetrically placed holes. A special releasing tool that has complementary protrusions for interfacing with the holes is required in order to decouple the locking piece from the valve.
