Violet ★★★★★

Finally found HNBR o-rings that actually hold up in my constant-hot-oil application—the 80 durometer feels just right, not too stiff. Was a bit skeptical about the temperature range, but after a month at 250°F they still look brand new with zero swelling.

Kevin R. ★★★★★

I've been running these in a hot hydraulic system that cycles between 150°F and 200°F, and so far no leaks after a week of steady use. The 80 durometer feels firm but not brittle, and the fit on the 2.049" bore was spot-on. Definitely stiffer than Buna-N but worth it for the heat resistance.

Hazel ★★★★★

The temperature range on these is exactly what my compressor rebuild needed, and the 80 durometer feels properly rigid out of the bag. I've got a full 40-pack to spare for future leaks, which makes the price feel fair for the quality.
