1/4"-28 Threaded Grease Fitting
This 1/4"-28 threaded grease fitting provides a permanent lubrication point for mechanical systems. It installs directly into a matching tapped hole to accept a standard grease gun coupler. The fine thread pitch ensures secure engagement in machinery and automotive applications. Mechanics and maintenance technicians use it to simplify routine bearing and joint servicing.
18-8 Stainless Steel Construction
The fitting body is made from 18-8 stainless steel for corrosion resistance in wet or chemical environments. Its 7/16" hex base allows standard wrench installation without rounding. The 7/8" overall length positions the nipple for clear grease gun access in confined areas. The hardened ball check valve retains lubricant and excludes contaminants after each use.
Replaces Damaged or Missing OEM Fittings
This part restores lubrication capability on equipment where the original fitting has corroded, stripped or broken off. It upgrades carbon steel fittings that rust and seize in marine, agricultural or food-processing settings. The jump is worth it when the mating thread is 1/4"-28 and the service environment demands stainless durability. It does not fit metric threads or 1/8" NPT ports.

Questions about this item
What thread standard does the 1/4"-28 grease fitting use?
The fitting uses a 1/4"-28 fine thread for permanent installation into a matching tapped hole.
What are the physical dimensions needed for the fitting to fit and mount?
The body measures 7/16" across the wrench flats and 7/8" in overall length, requiring a 1/4"-28 tapped port.
How is the stainless steel grease fitting installed, and what step is often missed?
Thread the 1/4"-28 fitting into the port by hand, then tighten with a 7/16" wrench; the missed step is cleaning the port threads first to prevent cross-threading.
