حلقات O من السيليكون | AS568-171 | داش 171 | متوافقة مع FDA | صلادة 70 | أحمر (18/عبوة)

The temperature range is what sold me—these handle -80°F to +450°F, so they’ll survive both my freezer and engine bay without cracking. That bright red color also makes them easy to spot during a quick inspection.

Used these red silicone o-rings to replace old seals on my sous vide circulator; they handled the heat beautifully without any degradation. The 70 durometer feels just right for a snug seal that isn’t too stiff to install.

The o-rings fit perfectly into my vacuum seal ports, and the 70 durometer gives them just enough flexibility without being flimsy. The high temp range to 450°F gives me confidence they'll hold up in my hot water system.
