Customer Reviews (4.6 / 5 · 5 reviews)

Evelyn ★★★★★

Finally found some o-rings that can handle the freeze-thaw cycles in my lab equipment without cracking. The 11 durometer PTFE is noticeably stiffer than rubber but seals perfectly in the groove.

Aurora ★★★★★

Finally, o-rings that can handle the -350°F side of things without turning brittle; I’ve already got a set on a cryo line and they’ve held their seal through three thermal cycles. The 11 durometer is noticeably softer than standard PTFE, which made seating them in the groove a breeze.

Scarlett C. ★★★★★

I needed a seal that could handle extreme heat, and these PTFE o-rings fit the bill perfectly. The 11 durometer feels surprisingly firm yet flexible, and the 0.611" ID seated snugly in my valve assembly.
