Customer Reviews (4.6 / 5 · 5 reviews)

Abigail ★★★★★

Finally found o-rings that actually hold up under high heat — the 450°F rating gave me peace of mind for my steam valve application. The red silicone is noticeably firmer than the black rubber ones I was using before. Fit perfectly on the first try, no wrestling needed.

Leo ★★★★★

These hit the spec dead-on and the red color makes them easy to spot during assembly. The 70 durometer feels just right for a snug seal without being a wrestle to install.

Eli O. ★★★★★

These seals handled the hot oil line without any drama, and the -80°F to +450°F range means they'll work year-round in my shop. The red color makes them easy to spot during assembly, and they didn't tear when I stretched them over the flange.
