1/4"-28 Stainless Grease Fitting
This 18-8 stainless steel grease fitting uses a 1/4"-28 fine thread for permanent installation in mechanical systems. It provides a nipple connection that accepts a standard grease gun to deliver lubricant under pressure.
Threaded Installation With Grease Gun
The fitting installs by threading the 1/4"-28 connection into a prepared port, leaving the nipple exposed for the grease gun. Cross-threading during installation can damage the threads and prevent a proper seal.
Maintenance Points Requiring Pressurised Lubrication
Suitable for equipment where a 1/4"-28 fine-thread port is specified and corrosion resistance is needed. Not suited for applications requiring a different thread pitch, a larger body size, or a button-head or drive-type fitting.

Questions about this item
How can I confirm the 1/4"-28 thread is sealing properly after installation?
Pump grease through the 37442 fitting with a standard grease gun; fresh grease should appear at the bearing or joint without leakage around the 18-8 stainless steel threads.
Does the package include a grease gun or only the 35/64" hex nipple fitting?
Only the 7/16" thread-length grease fitting is supplied; a compatible grease gun and grease cartridge must be purchased separately.
When should I choose the 1/4"-28 fine-thread version instead of a coarse-thread alternative?
Select this 28 TPI fine-thread model when the tapped hole in your machinery is cut to 1/4"-28; coarse threads will not engage correctly.
