Sebastian H. ★★★★★

These white o-rings are a perfect fit for my food-grade diaphragm pump rebuild. The shape held up exactly as expected under hot water, and the material seems much more durable than standard black rubber ones. Really glad I found a size this specific in a genuine Viton blend.

Joshua ★★★★★

The 60 durometer is noticeably firmer than the old 50A seals I'd been using, so these seat really well in my hot water valve with no leaks so far. Nice to have an FDA compliant white material that I can visually check for contamination.

Lucy ★★★★★

These replaced the old black ones in our lab's high-temp filtration setup, and they seat perfectly without any deformation. The bright white color makes it easy to spot if one gets knocked out of place during cleaning.
