Customer Reviews (4.8 / 5 · 5 reviews)

Eli F. ★★★★★

The red color makes them super easy to spot on the bench, and the 70 durometer feels just right for a snug seal. I popped one on a flange that's seen better days and it's holding firm without any leaks.

Daniel E. ★★★★★

Needed o-rings for a hot water application and these handled 200°F without any softening or swelling. The cross-section feels noticeably more consistent than generic hardware store rings.

Victoria F. ★★★★★

The red color made them easy to spot during a rebuild, and they slid into the groove without any twisting. Handled the 400°F oven test fine, and the 70 durometer feels just right for a snug but workable seal.
