حلقات O من السيليكون | AS568-905 | داش 905 | متوافقة مع FDA | صلابة 70 | أحمر (400 / عبوة)

The temperature range is what sold me—I can use these in both my cryo setup and hot water lines without swapping parts. The red color makes them easy to spot on the bench, and the bag of 400 will last me years.

The 70 durometer feels just right for sealing my pressure cooker valve—firm enough to hold but not brittle. Nice to have these FDA compliant rings on hand for any food-grade application that comes up.

I needed o-rings for a plumbing fix that had to handle hot water, and these silicone ones fit perfectly and held up without any swelling. The bright red color also made them easy to see during installation.
