Customer Reviews (5.0 / 5 · 5 reviews)

Emma ★★★★★

These handled the heat on my espresso machine steam valve perfectly—no more melting like the old Buna-N rings. The 70 durometer feels pliable enough to seat easily but should hold up under the 400°F rating.

Victoria ★★★★★

I needed a replacement for a high-heat seal in a compressor, and these Viton rings handle the 400°F max perfectly. The 4.484" ID fit my groove snugly right out of the package.

Alexander T. ★★★★★

The 0.139" cross-section on these is noticeably precise, and they sealed perfectly on my hot oil line that runs near 350°F. I've already ordered another set.
