Keep a variety of grease fitting shapes, styles, and sizes on hand. These fittings are also known as hydraulic grease fittings.

Zinc-plated steel fittings have mild corrosion resistance. 303 stainless steel fittings are more corrosion resistant than steel 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.

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.

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.
