Not the Intended Use, but Works
Bought this for a SnapOn/Williams screwdriver mod as talked about on GarageJournal. Fits in the void left by removal of the retaining ring well and keeps the ratcheting mechanism in place. If you're here for that, you've found the right one

These are hard to find for my vehicle
Works as expected. These seals were purchased for a 2004 Pontiac GTO. Installed a new radiator and the cooler lines for the transmission started leaking at the radiator. I don't know how I lucked out on the first radiator as that one didn't have seals either. These fixed the leak!

Worked Great
Perfect fit for the transmission cooler return line on a 1st gen Chevrolet Cruze. I replaced when I did a fluid change.
