Flush-Style Grease Fittings
The nipple doesn't stick out, so these fittings fit in tight spaces and won't be damaged if something knocks into them. 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.
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.
Install Styles A, B, and D with a slotted screwdriver. Install Style C with a hex wrench.
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.

Flush-Style Grease Fittings for Unthreaded Holes
Since they don’t protrude, these fittings avoid damage from impact and fit in tight spaces. Use a hammer and grease fitting installation tool (not included) to drive them into unthreaded holes. 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.
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.

Self-Tapping Flush-Style Grease Fittings for Unthreaded Holes
Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use them in tight spaces where protruding fittings won't work. 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. 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.
