Joseph ★★★★★

Finally, o-rings that actually hold up at the 400°F mark without getting brittle. The brown Viton material feels more substantial than the standard black ones I've tried before.

Owen ★★★★★

Used these in a high-temp compressor application where standard Buna-N kept failing, and the Viton FKM held up perfectly even above 300°F. The 75 durometer felt firm but not brittle during installation, and the brown color actually makes them easy to spot among other seals.

Claire ★★★★★

Installed these in a hydraulic fitting on my shop press last week and the 75 durometer hardness feels noticeably tougher than the standard Buna-N I'd been using. No leaks so far despite constant 300°F exposure.
