Alemite 310048 Grease Gun Locking Sleeve

Product Description

The ALEMITE 310048 is a replacement locking sleeve designed for use with grease guns. The locking sleeve secures the coupler to the grease fitting during lubrication, maintaining a sealed connection and preventing blowoff under pressure. This component is a direct-replacement part for technicians servicing or rebuilding grease gun assemblies. Lubrication technicians and fleet maintenance professionals rely on this part to restore full function to a worn or damaged grease gun without replacing the entire tool.

The 310048 locking sleeve is suited for use in fleet maintenance shops, industrial facilities, and field service applications where grease guns are used regularly for equipment lubrication. It is typically installed during grease gun rebuild or repair when the original sleeve shows wear, cracking, or fails to hold the coupler securely on a zerk fitting. The part ships in a quantity of one.

Key Features

• Replacement locking sleeve restores secure coupler-to-fitting connection
• Prevents coupler blowoff during pressurized grease delivery
• Single-unit packaging allows for individual part replacement without buying a full kit

Installation Notes

Installation is typically performed by lubrication technicians or maintenance mechanics. Before replacing the locking sleeve, relieve all pressure from the grease gun and ensure the tool is empty or depressurized. Basic hand tools are generally sufficient for disassembly and reassembly. Follow the grease gun manufacturer's service instructions for proper component seating and reassembly sequence.
