حلقات O من السيليكون 0.21" CS × 5.475" ID | AS568-353 | داش 353 | متوافقة مع FDA | صلابة 70 | أحمر (18 / عبوة)

Exactly the o-rings I needed for a high-temp food processing line; the 70 durometer silicone is firm enough to hold a seal without being too stiff. They slid right onto the flanges and the red color makes them easy to spot during inspections.

These are going into my hot oil filter housings, and the red color makes them easy to spot during inspection. They slid into the groove without twisting, and the FDA-compliant silicone makes me confident they won't break down in food service.

The 0.21-inch cross-section feels perfectly uniform, and these red o-rings sealed my pressure cooker lid without any leaks. They're noticeably softer than the black ones I've used before, which made installation a breeze.
