Ruby ★★★★★

I’ve been using these o-rings in a hot oil application where standard rubber would fail, and the 90 durometer Viton handles the heat beautifully without softening. The 50-pack is great value for a solid seal.

Victoria Z. ★★★★★

These have been holding up perfectly in a hydraulic application where temperatures hit 350°F. The 90 durometer feels noticeably stiffer than the standard Buna-N I replaced, and they seated without a fight.

Olivia F. ★★★★★

I needed a reliable seal for a high-temp hydraulic line and these Viton rings fit perfectly. The 90 durometer definitely feels stiffer than standard Buna-N, which is exactly what I wanted for the pressure.
