Sophia M. ★★★★★

The cross-section on these PTFE o-rings is exactly 0.103" as listed, and they slid into place perfectly in a cryogenic valve I was rebuilding. For the price per 75, you really can't beat the chemical resistance.

Christopher ★★★★★

The -350°F lower limit is impressive; I needed seals that wouldn't crack in my cryogenic test jig. These 11 durometer PTFE rings slid into place without any deformation and have held up perfectly through multiple freeze-thaw cycles.

Christopher ★★★★★

These o-rings are perfect for high-temp applications, the PTFE material feels durable and the -350°F to +500°F range gives me peace of mind. The 0.424" ID fit my assembly precisely with no leaks. I've already ordered another pack.
