Changing a propane cylinder can sometimes give the forklift operator a big surprise. If the seal in the cylinder valve fails, liquid propane gas can spray over the hand or face of the operator faster than they can react. Liquid propane vaporizes quickly (-420 C or -440 F) and will cause extreme frostbite if it touches skin. The quick change propane valve helps prevents LPG from coming in contact with skin and makes it easier to tighten and remove. In case of an LPG release, the liquid propane is directed away from the hand. The Easy-Grip ergonomic design allows you to hand tighten and loosen the coupler with less effort. The plastic nylon material works as an insulator from cold LPG or the brass coupler. Takes just 15 minutes to install - and lasts as long as the forklift!
