Richard ★★★★★

These o-rings feel nicely pliable yet firm thanks to the 70 durometer; I'm swapping them into a hydraulic cylinder. The 7.984" ID was a perfect match for my application, sealing tight on the first try.

George P. ★★★★★

Finally found o-rings that fit my 8-inch flanges perfectly; the 0.139" cross-section is just right for a snug seal. Installed a few already and they’re holding up well under normal temps.

Alexander ★★★★★

The metal-detectable feature gives me real peace of mind in my food processing line, and the 70 durometer is firm yet still seals nicely against those flanges. These fit a large pneumatic cylinder I was repairing, and the -40°F rating means they'll handle our cold storage area without issue.
