حلقات O من السيليكون | AS568-443 | داش 443 | متوافقة مع FDA | صلابة 70 | أحمر (8 / عبوة)

Pulled these out for a home brewing setup and the 70 durometer feels just right for the fittings. They seated snugly on the first try and have held up to the hot water cycles without any issues.

I needed a high-temperature seal for a steam exposure test, and these silicone rings held up perfectly at 400°F without any visible degradation. The red color also makes them easy to spot during assembly.

These o-rings handled a hot oil application at work without any softening, a big relief since the last batch failed quickly. The red color makes them easy to spot during inventory, and the 70 durometer feels just right for sealing.
