Eva ★★★★★

These 0.21" cross-section o-rings fit perfectly on my pump housing where thinner ones always leaked. The 70 durometer EPDM feels flexible yet firm enough to hold pressure even at 200°F.

Jacob K. ★★★★★

Finally, o-rings that actually seal my hot water line without swelling up—the EPDM holds up at 300°F way better than the old Buna ones I had. The 3.35" ID fit perfectly on my flange, and getting 26 in the pack means I've got spares for when I drop one behind the workbench.

Abigail ★★★★★

The -65°F rating meant I could stop worrying about this o-ring cracking in my outdoor hydraulic system. It seated perfectly in the gland and handled the pressure without any issue.
