Seesii Cordless Electric Grease Gun — 2026 Upgraded, 10,000 PSI, 2 Batteries, 39.4" Hose

The Seesii Electric Cordless Battery Grease Gun is a portable, high-pressure lubrication tool (up to 10,000 PSI) that delivers fast grease flow and comes as a complete kit with dual batteries, quick-release coupler, and a 39.4" flex hose for hard-to-reach fittings.

This upgraded 2026 kit is built for mechanics, farmers, and tradespeople who need a ready-to-use, battery-powered solution to replace hand pumps and cut grease job time. It pairs a durable industrial motor with user-friendly features — including three loading methods, an LED work light, and a compact hard case — so you can service cars, trucks, tractors, or heavy equipment without hunting for extras.

How much pressure and flow can I expect for stuck or stubborn fittings?

The Seesii grease gun produces up to 10,000 PSI and a high flow rate of about 6.4 ounces per minute, enabling it to push through hardened grease and clear blocked zerks faster than manual tools. The strong pure-copper motor keeps output steady during prolonged tasks so you won’t lose pressure mid-cycle.

• Maximum 10,000 PSI for high-resistance fittings
• 6.4 oz/min flow rate for faster lubrication cycles
• Industrial-grade pure copper motor for stable continuous output

What features make this kit easy to use on large jobs and in tight spaces?

Seesii included two 21V 2000mAh batteries so you can swap power packs for uninterrupted work on multiple machines. A 39.4-inch flexible hose plus a bright LED light allow precise access into blind or poorly lit joints, and the quick-release coupler locks securely to zerks to prevent leaks while you pump.

• Two swappable batteries for extended operation without downtime
• 39.4" flex hose and LED for reaching and seeing hidden grease points
• Quick-release coupler and standard coupler to fit most fittings

Which grease loading methods does it support and how do I avoid air locks?

The gun accepts 14 oz cartridges, 400cc bulk grease, or suction fill, so you can use whatever lubrication is on hand and switch methods as needed. A built-in bleeder valve makes removing trapped air simple, keeping flow consistent and preventing frustrating start-stop operation.

• Cartridge, bulk, and suction fill compatibility
• Built-in bleeder valve to quickly clear air locks
• Included pointed nozzle and couplers for flexible application

How portable and durable is this grease gun for field or shop use?

The package ships in a hard case with a shoulder strap for safe transport between job sites, and the ergonomic, lightweight body reduces hand and arm fatigue compared with manual guns. Heavy-duty construction and a stable motor make the tool suitable for repeated daily use on farms, garages, and construction equipment.

• Compact kit with hard case and shoulder strap for portability
• Ergonomic design to reduce hand fatigue during long tasks
• Robust housing and industrial motor for daily heavy-duty use
