Pro-lube ADPS9018M18FST5 Grease Fitting Adapter 90 Degree

Product Description

The PRO-LUBE ADPS9018M18FST5 is a 90-degree grease fitting adapter designed to convert a 1/8-27 female NPT port into a standard grease fitting connection point. Built from steel, this adapter accepts a grease fitting into its female NPT thread and redirects the lubrication pathway at a 90-degree angle, making it easier to reach fittings in tight or obstructed spaces. The 1/2-inch hex body allows for secure installation and removal with standard hand tools. Each package contains 5 adapters. Lubrication technicians, mechanics, and equipment service professionals use this adapter to restore or relocate grease access points on bearings, pivots, and other serviceable components.

This adapter is suited for use in industrial, commercial, and fleet maintenance applications wherever a grease zerk fitting needs to be installed at an angle to clear surrounding hardware or structure. The 90-degree head angle is particularly useful on equipment with closely spaced components or limited straight-line access to the lubrication point. The 1/8-27 NPT female thread is a common port size found on a wide range of machinery, vehicle chassis components, and HVAC equipment bearings. Installers working in shop or field conditions will find the steel construction appropriate for typical grease-gun service pressures and general-duty cycling.

Compatibility

Designed as an OEM-style replacement or supplemental adapter for equipment with 1/8-27 NPT female grease ports requiring a 90-degree fitting orientation.

Installation Notes

Installation should be performed by a qualified mechanic or lubrication technician familiar with NPT thread fittings. De-energize and secure any equipment before accessing lubrication points on rotating or moving components. Apply an appropriate thread sealant to the NPT threads per the equipment manufacturer's recommendations, and tighten using a wrench on the 1/2-inch hex - do not overtighten, as NPT threads are tapered and can crack fittings or damage ports. After installation, cycle the grease fitting with the service gun to confirm flow before returning the component to service.
