Customer Reviews (4.8 / 5 · 5 reviews)

Isabella J. ★★★★★

The high-temp rating on these o-rings gives me peace of mind for my steam application, and the 70 durometer feels just right when compressed. I used a whole pack seating several flanges and not a single one rolled or split during installation.

Steven B. ★★★★★

These red o-rings seated perfectly in my vacuum chamber flange. The 70 durometer feels just right for the application, and they've held up well with repeated heat cycling.

Grace G. ★★★★★

I needed a reliable seal for a hot water application, and these o-rings handle up to 450°F without any issue. The red color makes them easy to spot during assembly, too.
