Customer Reviews (5.0 / 5 · 5 reviews)

Leo A. ★★★★★

Was looking for an o-ring that could handle sustained heat near my compressor, and the 300°F rating on these finally gave me peace of mind. The 80 durometer feels just right—firm enough to seal without being a struggle to install.

Robert U. ★★★★★

Installed these HNBR o-rings in a high-temp hydraulic line that kept failing with standard rubber; the 80 durometer feels noticeably stiffer and the seal has held perfectly at 275°F for a week now.

Riley L. ★★★★★

Switched from standard Buna-N for a coolant line application and these HNBR o-rings are holding up much better at 250°F. The 80 durometer feels firm but still seals nicely without being a bear to install.
