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.

Straight

SAE-LT Thread—SAE-LT threads are tapered but designed to be installed into a _1/4"-28 straight-thread UNF hole.

NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.

Zinc-Plated Steel—Zinc-plated steel adapters have mild corrosion resistance.

303 Stainless Steel—303 stainless steel adapters are more corrosion resistant than brass adapters and have good chemical resistance.

Self-Tapping Grease Fittings for Unthreaded Holes

To fit securely in unthreaded holes, these fittings cut threads as they’re installed. Use a hex wrench to install. Fittings can be driven in, but then are not pressure rated. They're zinc-plated steel for mild corrosion resistance. All have an integral check valve that prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants. These fittings are also known as hydraulic grease fittings.
