حلقات O من السيليكون | AS568-152 | داش 152 | متوافقة مع إدارة الغذاء والدواء | صلابة 70 | أحمر (80/عبوة)

We replaced some older gaskets with these red silicone o-rings and the 70 durometer feels noticeably more pliable during installation. They hold up well under the heat cycles in our lab equipment, which easily hits the 450°F limit.

I’ve had these in the toolbox for a few weeks now, and the 70 durometer feel is just right—firm enough to hold a seal without being a pain to stretch into place. They’ve held up through a hot wash cycle and a quick freezer test, so the -80°F to +450°F range seems legit for everyday use.

The red color makes them easy to spot in my parts bin, and the 70 durometer feels like the perfect firmness for the water line repair I just finished. These silicone o-rings handled the hot water without any swelling.
