Plews Lubrimatic 05-031 Straight Grease Fitting 1/8 Npt

Product Description

The PLEWS LUBRIMATIC 05-031 is a straight grease fitting designed for use with standard jaw-type grease couplers on hand-operated lubrication equipment. The fitting threads into 1/8 inch NPT ports and incorporates a spring-loaded ball check valve that allows grease to flow under pressure while preventing backflow and contamination when the coupler is removed. With a recommended working pressure of 3,000 psi, this fitting suits routine chassis, bearing, and equipment lubrication tasks common in automotive, agricultural, and industrial service. It is not rated for use with power lubricating equipment.

This fitting is suited for any application requiring a straight-entry grease point at a 1/8 inch NPT threaded port. Typical installs include suspension components, steering linkages, universal joints, and other chassis lubrication points on trucks, trailers, agricultural equipment, and general industrial machinery. The straight body style is used where direct, in-line coupler access is available without the need for an angled or button-head fitting.

Installation Notes

Installation is typically performed by a mechanic or lubrication technician using a wrench sized to the fitting hex. Apply thread sealant appropriate for hydraulic fittings and tighten to snug without over-torquing the threads in the receiving component. Ensure the equipment or vehicle is safely supported and depressurized before replacing an existing fitting. Verify the replacement fitting body style and thread size match the original before installation.
