Pro-lube ANN/1-1-2 Needle Nose Grease Gun Adapter

Product Description

The PRO-LUBE ANN/1-1/2 is a needle nose grease gun adapter designed to deliver grease to hard-to-reach or recessed fittings that standard coupler nozzles cannot access. The adapter features a 1/8 inch NPTF female thread connection, a needle length of 1.5 inches, and a needle diameter of 0.156 inches (3.96 mm). A large locking sleeve secures the adapter to the grease fitting during application, preventing blowoff under pressure. This adapter is installed and used by lubrication technicians, HVAC mechanics, millwrights, and general maintenance professionals servicing equipment with tight or obstructed zerk fittings.

This needle nose adapter is suited for maintenance applications in residential, commercial, and light industrial settings where standard grease gun couplers cannot seat properly on recessed or closely spaced fittings. Typical use cases include electric motor bearing lubrication, HVAC blower shaft bearings, fan assemblies, and other machinery with limited fitting clearance. It threads directly onto most standard grease guns equipped with a 1/8 inch NPTF outlet.

Key Features

• Needle nose profile reaches recessed and hard-to-access grease fittings
• 1/8 inch NPTF female thread for secure, leak-resistant connection to grease gun
• 1.5 inch needle length provides extended reach into confined spaces
• Needle diameter of 0.156 inches (3.96 mm) for precision delivery
• Includes large locking sleeve to prevent coupler separation under pressure

Compatibility

Designed for use with grease guns equipped with a standard 1/8 inch NPTF outlet. The NPTF thread type provides a dry-seal fit compatible with most professional-grade grease gun models using NPT-standard connections.

Installation Notes

Thread the adapter onto the grease gun outlet by hand until snug, then tighten with a wrench to achieve a dry-seal connection - do not overtighten, as NPTF fittings seal on thread interference, not gaskets. Relieve any residual pressure in the grease gun before attaching or removing the adapter. Engage the locking sleeve fully onto the grease fitting before applying pressure to prevent blowoff. This component does not require specialized tools beyond standard hand tools and is a routine field swap for maintenance technicians.
