Keep a variety of grease fitting shapes, styles, and sizes on hand.

The nipple doesn't stick out, so these fittings fit in tight spaces and won't be damaged if something knocks into them.

Since they don’t protrude, these fittings avoid damage from impact and fit in tight spaces. Use a hammer and grease fitting installation tool to drive them into unthreaded holes.

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use these fittings in tight spaces where protruding fittings won't work.

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