Milwaukee M18 GG-0 M18 Grease Gun Bare Unit

When servicing heavy machinery, agricultural equipment, fleet vehicles or industrial plant, consistency and pressure matter. The Milwaukee M18 GG-0 is engineered to deliver powerful, controlled lubrication without the fatigue of manual grease guns.

Powered by Milwaukee’s M18 18V platform, this grease gun produces up to 690 bar maximum operating pressure, allowing it to handle stubborn or blocked grease fittings with confidence. Whether you’re maintaining excavators, tractors, HGV suspension systems or workshop equipment, the high-pressure output ensures reliable grease flow where lower-powered units struggle.

Designed for productivity, the M18 GG-0 is capable of dispensing up to 7 cartridges per charge (battery dependent), making it suitable for full service schedules without constant battery changes. The integrated air bleeder valve allows fast priming and reduces downtime caused by air locks — a common frustration in grease application.

The tool supports three-way loading:

• 400 ml grease cartridges

• 473 ml bulk grease

• Suction feed capability

This flexibility means technicians can adapt to site conditions or workshop stock without changing equipment.

Milwaukee has prioritised ergonomics and control. At only 355 mm in length and weighing approximately 3.9 kg with battery (M18 B2), the unit offers balanced handling during extended use. The integrated hose storage, shoulder strap loop, and LED fuel gauge improve convenience and jobsite efficiency.

Durability is enhanced through REDLINK™ overload protection, which safeguards both tool and battery from overloading. Individual battery cell monitoring helps optimise runtime and prolong battery life. The unit works with all Milwaukee M18 REDLITHIUM™ batteries, making it a practical addition for professionals already invested in the system.

This listing is for the bare unit, ideal for tradespeople and maintenance teams who already own compatible M18 batteries and chargers.
