Ryan ★★★★★

Used these in a high-temp compressor rebuild where standard Buna-N kept failing, and the Viton FKM held up perfectly at 375°F. The 70 durometer gives just enough flexibility to seat easily without feeling flimsy.

Nicholas ★★★★★

The 2.984" ID fit perfectly in my hydraulic manifold, and the Viton material feels much more durable than standard Buna-N. I've been running it at nearly 300°F for a week with zero leaks so far.

Christopher ★★★★★

I needed a reliable seal for a hot oil line, and these Viton O-rings handled the 350°F exposure without any softening. The 2.984" ID fit perfectly in my flange groove, and the 70 durometer felt firm but not too stiff.
