Assortments contain straight, 45° elbow, and 90° elbow fittings. These fittings are also known as hydraulic grease fittings.

Zinc- and zinc yellow-chromate-plated steel fittings have mild corrosion resistance. 18-8 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. 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.

Use these fittings in tight spaces where protruding fittings won't work. 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.

Install Style C with a hex wrench.

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.

Tap these tools once or twice with a hammer to install fittings.

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.

Zinc-plated steel adapters have mild corrosion resistance. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.
