Customer Reviews (4.8 / 5 · 5 reviews)

Aurora ★★★★★

These 90-durometer FKM rings handle the high-temp steam in my autoclave perfectly where standard Buna would fail. Installed a few dozen so far and they seat firmly without any deformation. Nice to have a full thousand pack for ongoing maintenance needs.

Brian J. ★★★★★

The -26°C low-temp rating was crucial for my outdoor gear setup, and these Viton FKM rings didn't get brittle in the cold. A full thousand pack means I won't need to reorder anytime soon.

Stella ★★★★★

These 90 durometer rings handled the 350°F steam in my autoclave without any visible swelling after a full cycle. The tight AS568-903 sizing seated perfectly in the groove the first time around.
