Madison ★★★★★

I was worried the 0.724" inner diameter wouldn't seat perfectly in my housing, but it slid in snug and holds pressure without a leak. The 70 durometer feels pliable yet tough enough for repeated compression, and the -65°F rating is exactly why I picked these over standard nitrile for my outdoor setu

Ryan ★★★★★

Installed these on a pneumatic actuator that sees daily thermal cycling, and the EPDM holds its seal perfectly through the -65 to 300°F extremes. The 70 durometer feels right for a snug fit without being impossible to stretch over the groove.

George ★★★★★

These arrived a little stiffer than some others I've tried, but that 70 durometer rating holds up perfectly under heat. I've had them on a steam port for two weeks now without any swelling or leaks. Just the right size for that 0.724" ID application.
