Adam Z. ★★★★★

The 90 durometer rating on these o-rings gave me a much better seal than the softer ones I tried before on a hydraulic fitting. The -15°F minimum is perfect for my outdoor gear that sees freezing temps.

Brian ★★★★★

I needed a high-temp seal for a steam line, and these FKM rings handled the 350°F cycling without any issues. The 90 durometer held its shape perfectly during installation. Exactly what I needed for that application.

Jacob Q. ★★★★★

The 90 durometer feels sturdy and pliable at the same time, and they fit perfectly on my valve stems. I've used these in a hot oil application reaching around 350°F and they haven't degraded at all.
