Customer Reviews (4.8 / 5 · 5 reviews)

Nicholas L. ★★★★★

The 70 durometer hardness feels just right for my application, and the 0.796" inner diameter seated perfectly in my groove without any forcing. Having 300 in the pack means I've got plenty of spares for the next few years of maintenance.

Aurora Y. ★★★★★

I needed o-rings that could handle temperatures down to -65°F for a remote hydraulic setup, and these EPDM ones arrive in bulk—300 in a package—so I have plenty of spares. The 70 durometer feels firm enough for a reliable seal in the groove.

Ellie ★★★★★

The 0.139" cross-section is beefy enough that these feel sturdier than the average o-ring I've handled, and the 300-pack should last me through years of projects. I've got them on a closed-loop heating setup right now and they're holding up fine at around 180°F without any swelling, which is exactly
