The MotoMaster Deluxe Pistol Grip Grease Gun offers the user the ease and benefit of one-handed operation. This is a huge advantage when working around confined spaces and with complex equipment. The user can position the coupler fitting with one hand while pumping the grease with the other. This unit will generate up to 7,000 psi, allowing plenty of pressure to overcome most clogged or restricted grease fittings. The pump head deploys a patented designed grease port which improves grease uptake and reduces the effects of air pockets and other common grease output failures. The pump head is also equipped with one grease quick fill valve and one air bleed valve which are intended to reduce gun refill and priming times. This grease gun is designed for daily use and is built to last for years of carefree operation.
