حلقات O من السيليكون | AS568-447 | داش 447 | متوافقة مع FDA | صلابة 70 | أحمر (7 / عبوة)

Installed these in a high-temp fluid system and they haven't shown any sign of degradation after weeks of use. The 70 durometer feels just right for a reliable seal without being too hard to work with.

Needed a precise fit for a vacuum chamber seal and these 70 durometer rings seated perfectly, no leaks at all. The high temperature range is a bonus since I occasionally use heat in the process.

Needed to replace some o-rings in a food-grade pump, and these 70 durometer silicone ones sealed perfectly even after multiple cycles. The -80 to +450 range is exactly what I was hoping for, and they came well-packed.
