Grease Fittings for Unthreaded Holes
Drive these fittings into unthreaded holes with a hammer and grease fitting installation tool (sold separately). They're also known as hydraulic grease fittings.
Fittings with a serrated shank have a tighter grip than those with a smooth shank for a more secure fit in old or oversized holes.
Zinc-plated steel fittings have mild corrosion resistance. 303 stainless steel fittings are more corrosion resistant than zinc-plated steel fittings and have good chemical resistance.
Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

Self-Tapping Grease Fittings for Unthreaded Holes
Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Install with a hex wrench. 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.
PTF (Dryseal) threads are compatible with NPT threads. SAE-LT threads are tapered.

Flush-Style Grease Fittings for Unthreaded Holes
Use these fittings in tight spaces where protruding fittings won’t work. Drive them into unthreaded holes with a hammer and grease fitting installation tool (sold separately). They’re zinc-plated steel for mild corrosion resistance. An integral check valve prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
