حلقات O من السيليكون | AS568-430 | داش 430 | متوافقة مع FDA | صلابة 70 | أحمر (14 / علبة)

The 70 durometer feels just right for my application, and the red color makes them easy to spot during assembly. These held up perfectly at 400°F in a test run.

I needed o-rings that could handle some pretty extreme temperature swings in my setup, and these silicone ones with the 70 durometer feel solid. The fact that they’re FDA compliant gives me peace of mind for my application, and the red color makes them easy to spot during maintenance.

The high temperature rating of 450°F is exactly what I needed for my oven control panel application. These red silicone rings fit perfectly on the first try, and the 70 durometer feels sturdy without being too hard to install.
