Mia ★★★★★

I had been searching for o-rings that could handle temps above 300°F, and these Viton FKM seals with their 400°F rating fit the bill perfectly. The 2.234" inner diameter matched my application exactly, and the 75 durometer feels sturdy yet flexible enough to seat properly. No leaks after a week of u

Daniel ★★★★★

I needed a seal that could handle hot oil in a small compressor, and these o-rings have held up perfectly at 300°F without any softening. The 0.139" cross-section gives a nice, snug fit in the groove.

Penelope ★★★★★

The 75 durometer feels just right for a solid seal without being too stiff to install. I’m using these for a high-temp valve rebuild, and the -15°F to +400°F range gives me peace of mind. They fit the groove perfectly and seem much more durable than the old Buna-N rings.
