About Grease Fitting Threads
More
Grease Fitting Cleaning Tools
Fill these tools with light oil, then tap with a hammer to open clogged fittings. The tapping action forces oil through the fitting and removes contamination from bearings, joints, and other parts. Use the included extension hose for hard-to-reach fittings.

Grease Fitting Adapters
When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
Zinc-plated steel adapters have mild corrosion resistance. Brass adapters are more corrosion resistant than zinc-plated steel adapters. 303 stainless steel adapters are more corrosion resistant than brass adapters and have good chemical resistance.
PTF and NPTF (Dryseal) threads are compatible with NPT threads. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage. SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.
