Lincoln's Grease Gun, No. G103, unlike other 3-ounce (85 g) models, incorporates the traditional lever-action design, which provides better handling and output pressure up to 6,000 psi (414 bar). The lightweight grease gun features a jam-proof handle mechanism, cast-aluminum head, powder-coated barrel and a comfortable vinyl grip. It uses 3-ounce cartridges, or it can also be hand packed or bulk filled. The tool comes with a replaceable grease coupler and rigid extension. Optional 12" and 18" (305 and 457 mm) flex hoses can be purchased.
