Brian M. ★★★★★

These 22-durometer rings are noticeably more flexible than the standard PTFE I’ve handled before, which made seating them into the groove a breeze. The -350°F to +500°F range gives me serious confidence for my cryo test rig, and the 18-pack means I’ve got spares for days.

Evelyn O. ★★★★★

Installed one on a high-temp steam valve that keeps chewing up rubber o-rings, and this PTFE held up perfectly after a week of cycling. The 22 durometer gives just enough flexibility to seat without cracking. Exactly what I needed for that application.

Evelyn ★★★★★

I was skeptical about using PTFE for a high-temperature seal, but these 22 durometer rings handled the 400°F test without any deformation. The 1.734" inner diameter fit perfectly on our flange, and the package of 18 was enough for the whole job.
