Alemite B6652-A Grease Gun Hose Coupler Assembly 4800 Psi

Product Description

The ALEMITE B6652-A is a grease gun hose coupler assembly designed for high-pressure lubrication service in professional maintenance and industrial applications. Measuring 12 inches in length with a 1/8 NPTF threaded connection, it handles operating pressures up to 4,800 psi. The assembly provides a reliable, leak-resistant link between the grease gun and the fitting, making it a standard component for lubrication technicians, mechanics, and field service professionals who need consistent grease delivery under demanding conditions.

This coupler assembly is suited for use with hand-operated grease guns in residential maintenance, fleet service, agricultural equipment, and light industrial settings. The 1/8 NPTF thread provides a pressure-tight, dryseal connection compatible with hydraulic fittings commonly found on chassis zerks, bearing housings, and similar lubrication points. Its 12-inch length gives technicians enough reach to access fittings in tight spaces without repositioning the gun body.

Key Features

• Rated to 4,800 psi maximum operating pressure for high-pressure grease gun service
• 12-inch length for extended reach to recessed or obstructed lubrication fittings
• 1/8 NPTF dryseal thread for a pressure-tight connection without sealant tape
• Compatible with hand-operated grease guns and standard hydraulic fittings
• Sold individually — single-unit packaging suitable for direct replacement or stocking

Compatibility

Designed for use with hand-operated grease guns and compatible with hydraulic fittings using a 1/8 NPTF thread connection. Suitable as an OEM-style replacement coupler assembly for standard grease gun setups in this thread and pressure class.

Installation Notes

Installation is typically performed by lubrication technicians or mechanics using basic hand tools. Relieve all pressure from the grease gun before disconnecting or replacing the coupler assembly. Verify that the 1/8 NPTF thread on the mating fitting is clean and undamaged before threading the assembly into place. Do not exceed the rated 4,800 psi maximum operating pressure during service.
