Robert B. ★★★★★

After struggling with standard o-rings that couldn't handle high heat, these PTFE ones seated perfectly in my application and haven't softened at all during repeated thermal cycles up to 300°F. The 22 durometer is noticeably more pliable than the typical stiff PTFE I've used before.

Henry A. ★★★★★

Finally found a proper 22 durometer PTFE seal that doesn't deform under extreme heat—the cross-section is exactly 0.139" as stated. These nested perfectly into my cryogenic valve assembly and held pressure effortlessly at -300°F.

Jason P. ★★★★★

The temperature range on these PTFE o-rings is exactly what I needed for a high-heat application; they slipped into place without any issue. These 220 size rings have a nice, consistent cross-section that seals perfectly. Really glad I found these for the price.
