حلقات O من السيليكون | AS568-928 | داش 928 | متوافقة مع FDA | صلابة 70 | أحمر (100 / عبوة)

The temperature range of -80°F to +450°F is exactly what I needed for a high-heat gasket application, and the 70 durometer silicone feels durable but flexible enough to seal well. These o-rings fit perfectly into my valve assembly and have held up without any degradation so far.

Needed a high-temp seal for a homebrewing setup, and these 70 durometer silicone rings handled boiling water without any softening. The -80°F to +450°F range gives me confidence for future uses, and the pack of 100 will last ages.

Finally found a batch of 70-durometer silicone o-rings that actually fit the AS568-928 groove on my hot water shutoff valve; the red color makes them easy to spot during maintenance. They're handling the 200°F steam exposure without any swelling or cracking so far, which is exactly what I needed.
