Olivia A. ★★★★★

I needed a Viton o-ring that could handle higher heat than standard rubber, and this one’s 400°F rating fits the bill perfectly. It seated cleanly on a steam valve flange without any distortion. The 7.984-inch inner diameter was spot on for my application.

Avery ★★★★★

The 75-durometer Viton feels firm yet flexible enough to seat properly in the groove without fighting me. I needed something that could handle the 400°F upper limit for a hot oil line, and these have held up perfectly so far after a week of steady use.

Chloe ★★★★★

At 7.984 inches ID, the fit was spot-on for my flange. These Viton rings held up perfectly at 350°F, no softening or deformation after a week of constant service. The 75 durometer feels stiff enough to seat well without fighting you during install.
