In The Fuel Gasoline is the safest cutting fuel. It is a totally stable, inert liquid. As a confined liquid it cannot burn-only its vapors can burn. It is impossible to backflash up the fuel line because the fuel is delivered in a liquid form all the way to the tip.
Any flame front trying to enter the tip is blocked by a wall of liquid gasoline.
Each tank is individually certified that it fulfills ASME quality standards. Standard features include pressure gauge, air pump, filter cap with a pressure relief valve, and a fast flow check valve that immediately shuts off the fuel if the hose is damaged. They can be handled immediately upon removal from the work area. Tips do not explode and seldom burn out. The tank can be filled at any gasoline pump in seconds.
