Alemite Lever-Action Grease Gun 500-E — 18" Flexible Hose, 10,000 psi, 16/24 oz Capacity

The Alemite 500-E is a professional lever-action grease gun that delivers up to 10,000 psi through an 18" flexible hose for precise lubrication in tight areas.

This compact, hand-operated grease gun pairs a rugged die-cast aluminum head with three-way loading and a comfortable vinyl-covered lever to make routine and heavy-duty lubrication faster and more controlled. Built for shops, fleets, and field technicians, the 500-E accepts cartridges or bulk fill and includes a bleeder valve to prevent pressure buildup. Its combination of high pressure and an 18" whip hose helps you reach fittings on vehicles, machinery, and equipment without cumbersome repositioning.

How does the 500-E produce enough force for heavy equipment fittings?

The 500-E uses a lever-action mechanism tuned for high-pressure output, generating up to 10,000 psi to push grease through tight lines and clogged fittings. The gun dispenses about one ounce every 21 strokes at standard volume, giving you predictable delivery for accurate lubrication.

• 10,000 psi maximum pressure for heavy-duty tasks
• Standard-volume lever action for controlled grease output
• Consistent rate: approximately 1 oz per 21 strokes

What loading options are available and how do they save time?

The 500-E supports three loading methods—14 oz cartridge, suction fill from bulk, or quick refill using an Alemite loader pump—so you can choose what fits your workflow. Cartridge loading reduces mess and downtime, while suction or loader pump refills are better for high-use environments.

• Cartridge loading for fast, clean swaps
• Suction fill from bulk grease for extended jobs
• Loader-pump compatible for rapid, high-volume refills

Can I reach fittings in cramped or awkward positions?

Yes—the included 18" flexible hose and threaded coupler let you access recessed or angled grease fittings without removing components. The whip hose flexes around obstacles while the coupler provides a secure connection to standard Zerk fittings.

• 18" flexible hose to reach confined spaces
• Secure coupler for standard grease fittings
• Flexible routing reduces need to reposition equipment

What features improve durability and user comfort on the job?

Alemite built the 500-E with a die-cast aluminum head to balance strength and low weight, and a vinyl-covered lever for a non-slip grip during extended use. A bleeder valve protects the cylinder from excess pressure, improving safety and helping maintain consistent performance over time.

• Die-cast aluminum head: durable and lightweight
• Vinyl grip for improved handling and fatigue reduction
• Bleeder valve prevents overpressurization of the cylinder

Who is this for? The Alemite 500-E is aimed at professional mechanics, maintenance technicians, fleet managers, and serious DIYers who need a dependable, high-pressure manual grease gun. If you regularly service vehicles, construction or agricultural machinery, or industrial equipment and require access to hard-to-reach fittings with precise, repeatable delivery, the 500-E is designed to handle those demands while offering multiple loading options and durable construction.
