A cap ( 100 ) having threads ( 109 ) along a rim ( 107 ) of an opening ( 105 ) in an end of a body ( 101 ) screws on a faucet ( 300 ) having complementary threads ( 311 ) on which a packing nut can be installed. A cavity ( 103 ) inside the body ( 101 ) is capable of receiving and covering a valve stem ( 307 ) to prevent the unauthorized use of the faucet ( 300 ). A securing member, such as a screw ( 113 ) that passes through a hole ( 115 ) in the body ( 101 ), secures the cap ( 100 ) to the valve stem ( 307 ) to prevent removal of the cap ( 100 ) from the faucet ( 300 ).
