The Matco Tools Transfer Gun With Clear Tube Barrel, No. FETG1, is ideal for easily transferring hydraulic oil, engine oil, fuel oils, and other non-corrosive liquids that are unsafe for body contact. The transfer gun draws in and pumps out liquid in one stroke. Features a rugged aluminum head with a tough, polycarbonate clear tube barrel to identify the fluid in the gun, eliminating the risk of mixing incompatible or unspecified fluids. The V-shaped drop resistant aluminum plunger handle is designed to prevent fluids from leaking.
