Ryan Y. ★★★★★

Put the dash 372 on a large air compressor I was rebuilding and it sealed perfectly on the first try. The 70-durometer material feels durable but not overly stiff, and the cross-section sits nice and snug in the groove.

Ella I. ★★★★★

Working on a hydraulic cylinder that kept weeping, and these 10.225" ID Buna-N o-rings sealed it up tight on the first try. The 70 durometer feels just right, not too hard to compress. Saved me a lot of headache versus chasing leaks.

Lily S. ★★★★★

Finally found o-rings that actually fit my industrial pump without leaking—the 10.225" inner diameter is spot on. I've been using them for a week at around 180°F and the Buna-N material is holding up perfectly.
