حلقات O من السيليكون | AS568-902 | داش 902 | متوافق مع FDA | صلابة 70 | أحمر (400/عبوة)

I needed a batch of o-rings that could handle both hot and cold extremes, and these red silicone ones fit perfectly—the 70 durometer feels just right for my sealing applications. The pack of 400 was more than enough for several projects, and they arrived without any damaged pieces.

The temperature range on these is the real selling point for me. I've used them in both a hot manifold and a cryo setup without any cracking, and the 70 durometer feels just right for a snug seal.

I needed some high-temp o-rings for a home brewing setup, and these silicone ones handling up to 450°F fit the bill perfectly. The 70 durometer feels just right—not too stiff, not too soft—and the pack of 400 should last me years.
