Joshua P. ★★★★★

I needed these for a high-temperature seal replacement and the PTFE material handles the heat well, plus the 13 durometer is actually pliable enough to seat easily. They fit perfectly on the 2.049" ID groove.

Edward ★★★★★

These PTFE o-rings handle the 0.103" cross-section perfectly for my high-temp valve rebuild. The -350°F to +500°F service range gives me confidence they'll last.

William Z. ★★★★★

I needed o-rings for a cryogenic application, so the -350°F rating on these PTFE ones was exactly what I was looking for. They fit the 2.049" ID perfectly and the 25-pack gives plenty of spares.
