Needle Spring (39107/39108/39109)

I was pleasantly surprised by how smoothly the lever reset after each use with this spring installed. It snaps the needle back into place exactly as described, making operation feel much more controlled.

The counter pressure on this spring feels exactly right when I pull the lever, and the needle snaps back to close the nozzle every time without sticking. It's a small part but it's made a huge difference in how smoothly my tool operates now.

Bought this to replace a worn-out spring on an old grease gun, and it fits perfectly. The counter pressure feels just right, snapping the nozzle closed the moment I let go of the lever. Finally, no more messy drips on the floor.
