Natalie ★★★★★

Swapped out old Buna-N seals for these Viton rings on a compressor head running hot, and they've held tight through several 200°F cycles so far. The 70 durometer feels firm but forgiving during installation. Exactly the high-temp solution I needed.

Miles M. ★★★★★

These Viton o-rings fit perfectly on my hydraulic cylinder, handling the high heat without any issue. The 70 durometer gives a nice, firm seal without being too hard to work into the groove.

Claire ★★★★★

Oiled these up before sliding them onto a stainless flange, and the 0.139" cross-section fit snug without any wrestling. Viton's been holding fine at 300°F in our steam line for a week now—no swelling or leaks. Glad I grabbed the 25-pack, because I'll be using these in a few more spots.
