حلقات O من السيليكون | AS568-154 | داش 154 | متوافقة مع FDA | صلابة 70 | أحمر (55/عبوة)

Been using these for a high-temp gasket repair on an old engine, and they hold up well even when things get really hot. The red color makes them easy to spot among other hardware.

Dropped a few of these into my pressure cooker lid and they sealed perfectly even at high heat. The 70 durometer feels nice and firm without being brittle, and that -80 to +450°F range gives me confidence for all my canning needs.

I’ve been using these red silicone o-rings in a high-temp air compressor application, and they hold up perfectly at 400°F. The 70 durometer feels just right—firm enough to seal but not brittle. A solid value for a 55-pack.
