حلقات O من السيليكون 0.139" CS × 1.609" ID | AS568-223 | داش 223 | متوافق مع FDA | صلابة 70 | أحمر (100 / عبوة)

The red color makes them easy to spot in my parts drawer, which is more useful than I expected. These 70 durometer rings seated perfectly in my hot water manifold and haven't deformed after weeks of steam exposure.

Finally got these to replace a gasket on my pressure cooker and the 70 durometer red silicone seals perfectly without any leaks. The -80°F to +450°F range gives me peace of mind for both freezing and boiling applications.

Placed these on a high-temp manifold in my shop and the 70 durometer silicone held up perfectly at 400°F. They're noticeably softer than the Buna-N I used before, which made installation a breeze without any leaks.
