حلقات O من السيليكون 0.139 بوصة CS × 0.609 بوصة ID | AS568-208 | داش 208 | قابلة للكشف بالمعادن | صلابة 70 (50 / عبوة)

These work perfectly as a replacement for the seals on my autoclave's door, and the 50-pack will last me a while. The high-temperature silicone is a plus since it sees steam cycles daily.

The metal-detectable feature gives me peace of mind in our food processing line, and the 70-durometer silicone seals perfectly against hot water spray. I've used these for a month straight now and they still look brand new.

Finally, an o-ring that survives my autoclave cycles without cracking—the -80°F to +450°F range is the real deal. The metal-detectable feature is a smart touch for food-line inspections, though the 70-durometer feel is a bit stiffer than I expected.
