Zoe S. ★★★★★

The 70 durometer rubber has just the right amount of squish for my seal groove, and the -65°F rating gives me confidence for winter use. These o-rings are holding up great so far.

Benjamin ★★★★★

I needed a replacement for a worn-out gasket on an industrial valve, and the 10.734" inner diameter fit perfectly. The EPDM material handles the heat from our steam lines without any issue, which is a huge relief.

Matthew ★★★★★

The 70 durometer feels just right for my hydronic heating system — firm enough to seal but not too stiff. These fit perfectly into the groove on my circulator pump flange. Already ordered another pack for backup.
