ABSTRACT:
An apparatus is provided for protecting hand operable valves which have a hand wheel attached to the valve stem. A valve stem cover is provided having an attachment to the assembly of the hand wheel and the stem, and having an open-ended nipple section on its upper end for receiving the valve stem therethrough. The nipple is provided with a plurality of laterally projecting ribbed edges. A tubular flexible, rubber-like sleeve section attaches to the nipple by frictionally engaging the ribbed edges. A cap encloses the uppermost second end of the tube section so as to encapsulate the valve stem together with the tube and the valve stem cover.
