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.

Straight with Male Thread

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

Brass—Brass fittings resist corrosion better than zinc-plated steel fittings.

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

316 Stainless Steel—316 stainless steel fittings resist corrosion and chemicals better than 303 stainless steel fittings and can be used in saltwater environments.

Ball Check Valve—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.

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.

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.

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.

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.
