Jacob Y. ★★★★★

Just swapped out some old seals in my hydraulic press with these, and the -15°F to +400°F rating gives me confidence they'll handle the heat cycles without cracking. The 0.139" cross-section fit perfectly into the groove.

Zoe ★★★★★

The 75 durometer rating on these o-rings was spot on for my heat exchanger rebuild, and the brown color makes them easy to spot during installation. They slid into the grooves without binding, and the 400°F temp range gives me peace of mind.

John F. ★★★★★

I needed a high-temp seal for a compressor rebuild, and these Viton o-rings handled the 350°F test run without any issue. The 75 durometer feels firm but not brittle, and the brown color made them easy to spot during installation.
