Great Replacement for John Deere Hydraulic Couplers
I bought these O-Rings to replace the leaking seals inside the front hydraulic couplers on my John Deere 318. They fit perfectly and stopped the constant slight leaks with attachments plugged into them.

Worked in my Umarex Fusion...
Just bought these to use in the pressure valve in my Umarex Fusion CO2 .177 pellet gun. No leaks! The 25 count will last a while. I previously bought five of the black o-rings for the Fusion off of ebay for nearly the same $, and they did not work.
