Kevin ★★★★★

I needed o-rings that could handle extreme temperatures, and these PTFE ones with their -350°F to +500°F range are exactly what I was looking for. The fit on my AS568-135 groove was spot on, and they seal great without any deformation.

Alexander ★★★★★

These PTFE o-rings are incredibly stiff at 13 durometer, which made seating them in a high-temp flange a breeze compared to rubber ones I've used. They slid in without kinking and haven't deformed yet under the thermal cycling.

Daniel ★★★★★

I needed an o-ring that could handle extreme temperatures for a lab setup, and the -350°F to +500°F range on these PTFE ones is exactly what I was after. They fit perfectly into the groove and the 13 durometer feels pliable enough to seal well without being too stiff.
