حلقات O من السيليكون 0.103" CS X 0.424" ID | AS568-111 | داش 111 | متوافق مع FDA | صلابة 70 | أحمر (325 / عبوة)

I’ve been using these for a high-temp plumbing repair and the red color makes them easy to spot against dark fittings, which is a nice bonus. The 70 durometer silicone feels durable yet flexible enough to seat easily, and the -80°F to +450°F range gives me confidence they’ll hold up in my steam setu

These sit perfectly snug in my stainless steel brewing setup and the red color makes them easy to spot if one falls. Handled a 350°F pasteurization cycle without any noticeable change in feel or shape, which is exactly what I needed.

Finally, o-rings that don't harden up after a few months in my hot water setup; these silicone ones feel way more flexible than the black rubber ones I used before. The red color makes them easy to spot during maintenance, and the 70 durometer is perfect for a snug, leak-free fit.
