Seesii GR06CA 10,000 PSI Grease Gun with 18" Hose and Quick-Release Coupler

Some lubrication jobs are easy to reach, others call for pressure, control and a way to work around awkward angles. The Seesii GR06CA combines a gear-assisted lever with a choice of flexible or rigid access, helping you grease fittings on trailers, vehicles, mowers and heavy machinery with a setup suited to the task.

Its 18" flexible hose reaches into tight spaces, while the quick-release coupler makes connecting to a fitting straightforward. For maintenance that benefits from a manual, adaptable approach, this kit brings useful access options together in one grease gun.

Tech summary

The gear-assisted lever provides mechanical advantage to make pumping smoother and help reduce hand effort during extended jobs. With pressure up to 10,000 PSI, the gun is designed for demanding lubrication work, including fittings that are difficult to grease. A twist-style air bleeder helps release trapped air when loading and priming, supporting a steady flow of grease.

The 400cc / 14 oz barrel works with standard 14 oz grease cartridges or bulk grease and supports NLGI #0, #1 and #2 greases. That capacity helps keep maintenance moving between refills. The kit includes a 4-jaw coupler, pointed nozzle, rigid extension tube and 18" flexible hose, so you can choose an access method to suit the fitting and available clearance. Metal components, a reinforced spring and an ergonomic non-slip handle support controlled handling during workshop, farm and equipment maintenance.

What it works with

Use the grease gun for lubrication work on trailers, trucks, tractors, ATVs, mowers, farm equipment, vehicles and machinery. The supplied fittings and extensions make it practical to switch between a direct, rigid approach and the added reach of the flexible hose. For example, when servicing a mower deck or reaching a fitting around a vehicle’s underside, the flexible hose can help you approach from an awkward angle, the rigid tube offers another option where a firmer, straight reach is more suitable.

The gun accepts standard 14 oz cartridges as well as bulk grease, and is compatible with NLGI #0, #1 and #2 greases. Match the grease type to the lubrication requirements of the equipment being serviced. The quick-release coupler is designed to connect and disconnect easily while holding securely during pumping.

Practical tips

Before starting, load the barrel with your chosen grease and use the twist-style air bleeder during priming to help release trapped air. Select the flexible hose for restricted access or angled fittings, and the rigid extension or pointed nozzle when that style of reach suits the job. Seat the coupler on the grease fitting before pumping, then release it with the quick-release mechanism when lubrication is complete.

For regular upkeep across several machines, the larger barrel capacity and multiple access options help reduce interruptions and make it easier to handle different fitting locations with the same tool. The gear-assisted lever is especially relevant when a job involves repeated pumping, offering mechanical assistance through longer lubrication sessions.

Should you buy it?

Choose the Seesii GR06CA if your maintenance routine covers equipment with hard-to-reach grease fittings and you want one manual kit with flexible and rigid access options. Its 10,000 PSI capability, air bleeder, quick-release coupler and 14 oz capacity address practical parts of the job: building pressure, priming the barrel, reaching the fitting and keeping grease available. It’s a useful fit for hands-on servicing of trailers, vehicles, mowers and machinery, whether the work happens in a home workshop, on a farm or around heavy equipment.
