حلقات O من السيليكون 0.21" CS × 7.975" ID | AS568-363 | داش 363 | متوافقة مع FDA | صلابة 70 | حمراء (11 / عبوة)

The 210°F rating is exactly what I needed for my autoclave’s seal, and the red color makes them easy to spot during maintenance. They slid into the groove perfectly and haven’t leaked a drop after a dozen cycles.

These fit the lid of my pressure cooker perfectly after I measured carefully. The 70 durometer feels just right for a food-safe seal, and the bright red color makes them easy to spot when I drop one. So far they’ve held up through several high-heat canning sessions without any issues.

I needed a replacement for a worn gasket on a hot water line, and the 0.21" cross-section on these 7.975" o-rings was a perfect fit. They’re stiff enough to hold pressure but still flexible to seat easily, and the red color makes them simple to spot during maintenance.
