Customer Reviews (4.8 / 5 · 5 reviews)

Isabella ★★★★★

Finally found O-rings that hold up to the 400°F rating in our steam line without going brittle. The 90 durometer is stiff enough to seal properly but still easy to seat in the groove.

Chloe ★★★★★

Installed these in a high-temp air compressor setup and they haven't softened or deformed after weeks of 300°F cycles. The 90 durometer feels just right for that extra firm seal without being too stiff to work with.

Ava ★★★★★

These are sealing the hydraulic fittings on my press perfectly at 90 durometer, and the 1.859" ID is a spot-on match for the groove. I've had them on a line running near 350°F for two weeks now without a single weep.
