حلقات O من السيليكون | AS568-154 | داش 154 | قابلة للكشف المعدني | صلابة 70 (8 قطع/عبوة)

Was relieved to find these in the exact AS568-154 size for a high-temp sealing project I'm working on. The 70 durometer feels just right—firm enough to hold a seal but still flexible to install.

These worked perfectly for my sous vide circulator where standard rings kept failing. The -80°F to +450°F range gives me confidence across both hot water baths and cold storage. Much denser feel than the cheap silicone I've used before.

I needed a high-temp seal for a commercial oven door and these silicone rings handled the 400°F test without any deformation. The metal-detectable feature gives me peace of mind in a food processing area.
