Scarlett W. ★★★★★

The 80 durometer hardness feels just right for my application, and these HNBR rings handle the heat range I need without any softening. I've already used about 40 of them on a hydraulic fitting job and they seated perfectly every time.

Claire E. ★★★★★

I’d been having trouble with standard nitrile o-rings hardening in my hot oil application, but these HNBR ones at 0.103" cross-section have held up perfectly so far. The -40°F to 300°F temp range is exactly what I needed, and the 80 durometer feels firm without being brittle.

Amelia ★★★★★

The 0.103" cross-section seals perfectly in my compressor’s hydraulic fittings, and the 80 durometer feels firm without being too stiff. I've used about 30 so far with zero leaks, even at 250°F oil temps.
