حلقات O من السيليكون | AS568-415 | داش 415 | متوافقة مع FDA | صلابة 70 | أحمر (12 / عبوة)

I needed a replacement for a gasket that sees constant hot water exposure, and these red silicone rings haven't softened or stretched out after a month of use. The 70 durometer feels just right for a snug seal without being too stiff.

The temperature range on these is insane—I’ve got them holding up in a steam line that cycles way past boiling, and they haven’t cracked or deformed after a month of daily use. Red color makes them easy to spot during inspection, too.

I needed a batch of o-rings that could handle serious heat and cold swings, and the -80°F to +450°F range on these covers everything I throw at them. The red color makes them easy to spot during assembly, and the 70 durometer feels flexible yet holds its shape well.
