حلقات O-Ring من السيليكون CS 0.21 بوصة × ID 17.475 بوصة | AS568-388 | داش 388 | متوافقة مع FDA | صلابة 70 | أحمر (5 / عبوة)

Was a bit worried about the size before I measured, but the 17.475" ID is spot on for my application. These handle the heat cycles in our lab oven without any brittleness, and the red color makes them easy to spot during assembly.

These 70-durometer red rings fit perfectly on our steam table lid and the FDA compliance was a must for our kitchen. They seated well with no binding, and the -80°F rating gives me confidence for cold storage too.

Installed these in a high-temp food processing line and they've held up perfectly at 400°F so far. The 70 durometer is firm enough for a good static seal but still flexible to install.
