The Black Diamond Heavy Duty Lever Grease Gun delivers powerful, reliable lubrication with up to 8,000 PSI of pressure and an output of 1 oz per 28 strokes. Its variable-stroke lever design allows smooth operation in tight spaces where handle movement is limited. Built with a durable aluminum die-cast head fitted with a bulk loader valve and a tough powder-coated finish, it’s made for demanding use. Complete with a 6" steel extension and coupler, this grease gun supports 4-way loading and uses standard 14 oz cartridges with a 1/8" NPT threaded connection.
