Leo ★★★★★

That -350°F to +500°F range is exactly what I needed for a high-temp seal on a hot oil line. The 22 durometer PTFE feels firmer than rubber but still seated into the groove without any struggle.

Eva ★★★★★

These o-rings are surprisingly flexible for PTFE — the 22 durometer makes them easy to seat in tight grooves, and the temperature range from -350°F to +500°

Claire F. ★★★★★

Finally found o-rings that resist melting near our high-temp lab oven, and the 22 durometer PTFE is stiff enough to seal without cracking. The -350°F to +500°F rating gives me confidence for both cryo and heat cycles. These 2.109" ID rings fit perfectly on our flanged fittings.
