حلقات O من السيليكون | AS568-178 | داش 178 | متوافقة مع FDA | صلادة 70 | أحمر (12 / عبوة)

These came in the exact red color I needed for quick identification on a few lines that run hot. The -80°F to 450°F range gives me peace of mind knowing they'll hold up where cheaper rubber ones always cracked.

We needed a replacement o-ring for a high-temp water valve, and these 70 durometer silicone ones fit perfectly on the first try. The bright red color makes them easy to spot during installation, which is a nice bonus. They've been holding up great through several hot cycles with no signs of wear.

Even at 450°F these red silicone rings held up perfectly in my home brewing setup, and the pack of twelve was enough to replace all the worn seals on the keg fittings.
