Isabella A. ★★★★★

Used these to rebuild a hydraulic cylinder on my log splitter and they sealed up perfectly at 2000 psi. The 70 durometer feels like the right balance between flexibility and durability for that application.

Harper A. ★★★★★

These o-rings fit perfectly on a Parker fitting I was repairing, nice snug seal right away. The 70 durometer feels firm but not brittle at room temp, just what I needed for a fuel line application.

Joseph ★★★★★

Used them to rebuild a hydraulic cylinder on an old tractor and the -40°F rating handled the cold snaps perfectly. The 70 durometer feels durable without being too stiff. Exactly what I needed.
