Customer Reviews (4.8 / 5 · 5 reviews)

Sofia ★★★★★

The 80 durometer hardness feels just right for my hydraulic application, and the -40°F cold rating gave me peace of mind for winter operation. I’ve already used three of the 30 and they seated perfectly without any distortion.

Steven M. ★★★★★

Finally found HNBR o-rings that hold up in my hot oil pump application. The 80 durometer provides just the right firmness for that 2.234" ID, and thirty in a pack is plenty for a couple rebuilds.

Henry ★★★★★

I needed a reliable seal for a high-temp hydraulic application, and these HNBR rings handle the 300°F range perfectly. The 80 durometer feels just right for the pressure I'm running—no leaks at all.
