Pro-lube HC/R/01/N Grease Gun 90 Degree Coupler Npt

Product Description

The PRO-LUBE HC/R/01/N is a 90-degree grease gun coupler designed for use with standard grease guns in lubrication service applications. The coupler connects to a 1/8 inch NPT threaded fitting and is rated for an operating pressure of 1,000 psi. The 90-degree angle makes it easier to reach grease fittings in tight or restricted spaces where a straight coupler cannot align properly. Lubrication technicians, equipment mechanics, and fleet service professionals use this type of coupler during routine preventive maintenance on machinery, vehicles, and industrial equipment.

This coupler is suited for use in both light commercial and industrial lubrication service scenarios. It attaches to the end of a standard grease gun hose or rigid barrel outlet and mates with grease fittings in locations where access is limited by nearby components, frame rails, or housing geometry. The 90-degree configuration is a common requirement on agricultural equipment, heavy trucks, construction machinery, and HVAC fan shaft bearing assemblies that use grease-type lubrication points.

Key Features

• 90-degree coupler angle for access to restricted or hard-to-reach grease fittings
• 1,000 psi operating pressure rating supports standard grease gun output
• 1/8 inch NPT thread for compatibility with standard grease gun outlets and hose ends
• Compact, single-unit package suitable for field service kits and toolbox stocking

Compatibility

Designed as a replacement or supplemental coupler for standard grease guns equipped with a 1/8 inch NPT outlet connection.

Installation Notes

This coupler is installed by lubrication or maintenance technicians as part of routine greasing operations. Thread the coupler onto the grease gun hose or barrel outlet using the 1/8 inch NPT connection and ensure it is hand-tight before applying wrench torque to avoid cross-threading. Relieve any residual pressure in the grease gun before swapping couplers. Do not exceed the 1,000 psi rated operating pressure of the coupler during use.
