حلقات O من السيليكون 0.139 بوصة CS × 11.734 بوصة ID | AS568-283 | داش 283 | متوافق مع FDA | صلابة 70 | أحمر (6/عبوة)

For my food processing line, these silicone rings held up perfectly at 400°F without any warping. The 0.139” cross-section was just right for our flanges, and the red color makes them easy to spot during maintenance.

I needed a high-temp seal for a homebrew kettle valve, and these silicone rings handled boiling water with zero softening. The 11.734" inner diameter was exactly right for my application, and the bright red color makes them easy to spot during disassembly.

These fit my pressure canner lid perfectly, and the red color makes them easy to spot when I'm doing a quick visual check during setup. The silicone feels substantial and the 70 durometer rating gives me confidence they'll hold up for years.
