حلقات O من السيليكون | AS568-427 | داش 427 | متوافقة مع FDA | صلابة 70 | أحمر (14 / عبوة)

The red color makes them easy to spot during disassembly, and the -80°F to +450°F range gives me peace of mind for hot and cold applications. Each pack of 14 is enough for a couple of rebuilds, and the 70 durometer feels solid without being overly stiff.

These o-rings fit perfectly in my high-temp valve rebuild kit, and the red color makes them easy to spot during assembly. The 70 durometer silicone feels just right for a consistent seal without being too stiff. Nice to finally have FDA-compliant seals I can trust in a food-grade application.

Finally, o-rings that can handle my hot oil bath setup without degrading—these red ones took 400°F without a sweat. The 70 durometer silicone is firm but still seals nicely in the groove. Only ding is the 14-pack runs out faster than I'd like when you're replacing a whole valve assembly.
