Alemite 6243-J3E Lever Grease Gun 10000 Psi 24 Oz

Product Description

The ALEMITE 6243-J3E is a lever-action grease gun rated for up to 10,000 psi, designed for high-pressure greasing of fittings in industrial, fleet, and commercial service applications. It accepts a standard 24 oz cartridge and delivers grease at 20 strokes per ounce through a rigid pipe nozzle extension with a 1/4 inch NPTF outlet thread. Lubrication technicians, heavy equipment mechanics, and fleet service professionals use this tool for routine bearing, chassis, and fitting maintenance. The lever mechanism provides consistent stroke control, making it well-suited for high-cycle greasing tasks where repeatable output matters.

The 6243-J3E is used in shops, fleet yards, and field service environments where high-pressure grease delivery is required. The rigid hose configuration is preferred in fixed-position or bench greasing setups where a flexible hose would add unnecessary slack. Typical applications include agricultural equipment, construction machinery, automotive chassis fittings, and general industrial bearing maintenance. The included coupler and loader fitting allow for standard cartridge loading and fitting attachment without additional adapters.

Key Features

• Lever-action operation rated to 10,000 psi maximum operating pressure
• 24 oz cartridge capacity with cartridge-style refill loading
• 20 strokes per ounce for consistent, measurable grease output
• Rigid pipe nozzle extension for stable, direct fitting engagement
• 1/4 inch NPTF outlet thread for standard fitting compatibility
• Includes coupler and loader fitting — no additional adapters required out of the box

Compatibility

Designed for use with standard 14 oz and 24 oz cartridge grease formats via cartridge-load fill method. Compatible with standard NPTF grease fittings using the included coupler. Confirm fitting type and thread standard before use.

Installation Notes

Loading and servicing this grease gun should be performed by a qualified lubrication or mechanical technician familiar with high-pressure greasing equipment. Before attaching to any grease fitting, relieve pressure in the gun barrel and confirm the outlet coupler is fully seated to prevent blowoff under pressure. Inspect the rigid pipe extension and coupler for wear or damage before each use. Follow equipment manufacturer recommendations for grease type and fitting torque specifications — do not exceed the 10,000 psi rated operating pressure of this tool.
