Grease Fittings
Thread these fittings into motors, bearings, engine blocks, and other machinery to create a lubrication point. They’re also known as hydraulic grease fittings.
Zinc-plated steel fittings have mild corrosion resistance. 303 stainless steel fittings are more corrosion resistant than brass fittings and have good chemical resistance. 400 nickel fittings are the most corrosion resistant and can be used in caustic environments, such as those involving salt water, sulfuric acid, and alkalies.
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.
PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads.

Leakproof Grease Fittings
Keep thin grease from leaking out—the check valve in these fittings has a Buna-N seat that creates a tighter seal than check valves in other grease fittings. The valve stays closed when not in use to keep out dirt and other contaminants. Fittings are zinc-plated steel, which has mild corrosion resistance. They're also known as hydraulic grease fittings. They have PTF-SAE and NPTF (Dryseal) threads, which are compatible with NPT threads.
