Hazel H. ★★★★★

After a week in our 300°F autoclave these FKM rings haven't hardened or cracked at all, which is exactly what I needed for a high-temp steam seal. The 75 durometer feels just right—firm enough to hold pressure but not brittle.

Benjamin E. ★★★★★

Finally, a seal that holds up in our steam sterilizer without degrading after a few cycles. The 75 durometer feels just right—firm enough to seat properly, yet not brittle. These Viton rings are exactly what I needed for high-temp service.

Edward ★★★★★

I’ve been running these in a hot oil application that’s pushed them past 350°F, and they’re still sealing perfectly without any hardening. The metal-detectable feature is a nice safety bonus, and the 75 durometer feels plenty firm for the job.
