Isabella E. ★★★★★

I needed a 90 durometer o-ring for a high-temp fluid application, and these HNBR 334s fit perfectly in the groove. The 2.6" ID was exactly as specified, and the rubber feels dense and durable.

Elizabeth I. ★★★★★

These 90-durometer HNBR rings are perfect for my hydraulic cylinder repair—they fit the groove exactly and haven't leaked a drop under 150°F oil. The -40° to +300°F range gives me confidence for the tough applications.

Joshua ★★★★★

I needed a seal that could handle both high heat and cold, and these HNBR rings hit that -40°F to +300°F range perfectly. The 90 durometer feels plenty firm for my compressor rebuild.
