Nicholas ★★★★★

Installed these in a high-temp steam valve that kept eating standard Buna seals, and the -15°F to +400°F range has handled the cycling perfectly so far. The 3.239" ID was bang-on for my housing groove, and the 75 durometer feels firm but not brittle.

Ellie E. ★★★★★

Finally found the right size for a high-temp hydraulic line repair I've been putting off. These 3.239" ID rings fit perfectly and the 75-durometer Viton feels substantial.

Henry ★★★★★

I've been using these Viton o-rings in a hot oil application that spikes near 350°F, and they've held up perfectly without any swelling or cracking. The 75 durometer feels firm but not brittle, and the 60-pack is a solid value for industrial use.
