حلقات O من السيليكون | AS568-907 | داش 907 | متوافقة مع FDA | صلادة 70 | أحمر (325 / عبوة)

The temperature range on these things is wild—I've used them on a steam line and they didn't even soften. The 70 durometer is just right for a firm seal without being a pain to install.

These red silicone rings have a nice, firm feel to them, and the 70 durometer was exactly what I needed for my application. I was also impressed that they’re clearly FDA compliant, which gives me peace of mind for food-related use.

Used these red silicone o-rings to replace the seals on a hot oil pump at work, and they handle the high temps without issue. The 70 durometer feels just right—firm enough to hold pressure but still flexible enough to seat easily.
