حلقات O-Ring سيليكون 0.103 بوصة CS × 2.799 بوصة ID | AS568-149 | داش 149 | متوافق مع FDA | صلابة 70 | أحمر (80/عبوة)

The red color makes them a cinch to spot when I’m swapping parts, and the 70 durometer feels just right—firm enough to hold a seal without being a pain to seat. I’ve got a pack of 80 and they all stayed perfectly round out of the bag.

These handled the high heat of my autoclave without any visible degradation after a dozen cycles, which is exactly what I needed for my food processing equipment. The 70 durometer gives them just the right amount of squeeze without being too stiff.

The red color makes them easy to spot in my spare parts bin, and the -80°F to +450°F range means they handle both my hot water valve and freezer gasket without cracking. Installed a dozen on plumbing fittings today and none leaked on first try.
