Alexander ★★★★★

Switching from Buna-N to these HNBR o-rings for my hydraulic fittings, and the 90 durometer holds up noticeably better under the 300°F service spec. Even after a few hot-cold cycles, they’ve stayed pliable and haven’t leaked a drop.

Benjamin ★★★★★

The 90 durometer is perfect for my high-temp pneumatic application, and the -40°F rating gives me peace of mind. These HNBR rings sealed the air line on the first try with no leaks.

Brian ★★★★★

Popped one of these in a hydraulic fitting that's been leaking for weeks—the 90 durometer HNBR holds up much better than the standard Buna-N I was using before. No swelling or distortion after a solid week at 250°F. Exactly what I needed for a high-temp industrial application.
