حلقات O من السيليكون 0.07 بوصة CS × 5.239 بوصة ID | AS568-050 | داش 050 | متوافق مع FDA | صلابة 70 | أحمر (50 / عبوة)

Installed these on my brewery's hot liquor tank sight glass and the 70 durometer silicone feels plenty firm for the application. The red color makes them easy to spot during maintenance checks.

The -80°F rating is what sold me, since my outdoor gear sees brutal winters, and these red rings haven't cracked or stiffened at all. Sealed the flange perfectly on the first try, and the 5.239" inner diameter was dead-on accurate.

These handled the high-temp seal on my smoker perfectly, the red color makes them easy to spot during cleanup. The 70 durometer feels firm but still flexible enough to seat into the groove without fighting it.
