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. Brass fittings resist corrosion better than zinc-plated steel fittings. 303 stainless steel fittings are more corrosion resistant than brass fittings and have good chemical resistance. 316 stainless steel fittings resist corrosion and chemicals better than 303 stainless steel fittings and can be used in saltwater environments.
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.

Button-Head Grease Fittings
Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won’t pop off when adding grease. They're best for machinery requiring high volumes of grease because they let more grease pass through than standard grease fittings, thanks to a larger opening. 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.

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.
Install Styles A, B, and D with a slotted screwdriver. Install Style C with a hex wrench.

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.
Brass adapters resist corrosion better than zinc-plated steel adapters. PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads.
