Seesii Electric Grease Gun 12000PSI Cordless with 2 Batteries — 3-Speed, 39.4" Hose for Heavy-Duty Equipment

The Seesii 12000PSI electric grease gun is a cordless, high-pressure lubrication tool that delivers precise, adjustable grease flow for heavy equipment and routine maintenance.

Compact and battery powered, this Seesii grease gun replaces manual pumping with a single-button system and three selectable speeds to match light fittings or stubborn, clogged points. Supplied as a full kit with two batteries, multiple couplers, a long flexible hose and accessories, it’s built to keep tractors, trucks, mowers and workshop machinery serviced faster and with less fatigue.

How does the 3-speed control improve maintenance work?

The three speed settings let you balance speed against control so you avoid over-greasing sensitive parts while still delivering high flow when needed. Select low for delicate fittings, medium for everyday service, and high for tight or blocked joints.

• Low: precision dispensing for small or sealed grease points (approx. 5 oz/min).
• Medium: general-purpose rate for typical maintenance (approx. 7 oz/min).
• High: rapid delivery to clear clogged fittings and heavy applications (approx. 9 oz/min).

What accessories are included and why do they matter?

The complete kit arrives with everything needed to start work immediately and adapt to different grease fittings and environments. Multiple couplers and a long hose increase reach and versatility, while spare batteries reduce downtime on the job.

• Two 2000 mAh batteries and charger for continuous operation and quick swaps.
• 39.4" flexible hose plus 90° adapter to access awkward or recessed fittings.
• Quick-release, standard and sharp nozzles for broad compatibility.
• Extension pipe, shoulder strap, and hard case for transport and organization.

How easy is it to load and operate the gun?

Loading takes a few steps and supports both bulk grease and standard cartridges, so you can choose the most convenient supply for the task. The plunger and two-way fill design accept common cartridge sizes and NLGI #0–2 greases.

• Two-way fill for cartridge or bulk grease (cartridge standard 54mm diameter).
• Automatic continuous pumping via a lock-on trigger for hands-free use.
• Stable scratch-resistant base and integrated LED light for safer handling.

Will the gun hold up on heavy-duty jobs and in tight spaces?

Built for workshop and field use, the Seesii gun pairs a brushless motor with high pressure capability to handle demanding lubrication points. The flexible hose and included adapters make reaching suspension components, chassis joints and agricultural fittings straightforward.

• Brushless motor design for longer life and consistent pressure delivery.
• Up to 12000 PSI peak pressure to clear stubborn fittings (operational high-flow settings around 9 oz/min).
• Hose clip and shoulder strap protect the hose and reduce user strain during extended jobs.

Who this is for: The Seesii 12000PSI electric grease gun is aimed at farmers, fleet managers, mechanics, and serious DIYers who need a reliable cordless solution to speed up routine lubrication and tackle blocked or hard-to-reach grease points. If you service multiple machines per day or want to avoid manual pumping fatigue while keeping a range of fittings covered, this kit supplies the batteries, couplers and reach to get the job done efficiently.
