Evelyn Z. ★★★★★

I’ve been using these o-rings in a high-temp steam application where standard Buna-N failed quickly, and the -15°F to +400°F range is spot on—they’ve held up perfectly so far. The 90 durometer feels noticeably firmer than the 70s I’ve used before, which is exactly what I needed for a tight seal unde

Steven ★★★★★

Fit perfectly on my hydraulic fitting and the 90 durometer feels really solid. Handled the 350°F oil splash without any softening at all.

Lucy M. ★★★★★

I needed a high-temp seal for my espresso machine's steam wand valve, and these rings dropped right in. The 400°F rating gives me peace of mind during descaling cycles, and the 90-durometer feels a bit firmer than standard Buna-N, which seems to hold pressure better.
