Lily D. ★★★★★

These o-rings fit perfectly in my hydraulic fitting, and the 70 durometer feels just right for the pressure. I’m glad I went with the Viton FKM material since it sees temps up to 400°F in my setup. Good value for a 12-pack.

Kevin ★★★★★

I needed o-rings that could handle high heat near a furnace, and these have been performing flawlessly at over 350°F without any sign of degrading. The -15°F to +400°F range gives me confidence for winter shutdowns too.

Sebastian F. ★★★★★

The 70 durometer hardness feels perfect for my application, and the 1.859" inner diameter matched my groove exactly. These Viton rings handled a 350°F heat cycle without any deformation, which is exactly what I needed.
