The Lincoln Model 1134 delivers where other grease guns fail. The cast aluminum heads and enclosed piston assembly work together to produce a grease gun that withstands the abuse of even the harshest lubrication environments. While extremely durable, the 1134 is also very comfortable. Its unique design and special pivot angle significantly reduce user fatigue. Some additional features include a jam-proof handle return mechanism, rugged single piece head casting, filler coupler/bleeder valve combination, extra heavy follower spring, Lincoln exclusive flip over follower, three-way loading: cartridge, suction or bulk along with an 18" flexible hose with coupler and a rigid 4" tube.
