Abstract

A combination pressure measurement/refrigerant charging apparatus may include a shutoff valve that includes a piercing pin and a pressure gauge. The piercing pin may be used to pierce a refrigerant can. The pressure gauge may be used as a handle for operating the shutoff valve. A first end of a hose may be coupled to the shutoff. A quick coupling device may be coupled to a second end of the hose. The quick coupling device may be used to couple the apparatus to a refrigerant system.
