Victoria ★★★★★

Finally found some seals that actually hold up in my hot oil bath application. The 90 durometer HNBR material hasn't softened at all even after constant 250°F exposure.

Julian ★★★★★

These seals fit my pneumatic cylinder perfectly and the 90 durometer is noticeably stiffer than my last batch, which is exactly what I needed. They survived a full afternoon cycling at 275°F without any sign of softening.

Andrew ★★★★★

I needed a high-temp seal for a hydraulic cylinder in my shop press, and these HNBR rings fit perfectly and haven't softened at all under constant 200°F oil exposure.
