حلقات O من السيليكون | AS568-911 | داش 911 | متوافقة مع FDA | صلابة 70 | أحمر (250 / عبوة)

The red color makes them easy to spot during assembly, which saved me time on a recent rebuild. The 70 durometer provided the right balance of flexibility and sealing pressure, and the whole package of 250 should last me through several projects.

These handled the heat in my application without any softening or deformation, which was my main worry. The bright red color also made it easy to spot a seated ring during assembly. Solid buy for the price, especially with 250 in the pack.

Exactly what I needed for replacing old gaskets on my lab equipment — the red color actually makes it easier to spot leaks during inspection. The -80°F minimum rating gives me confidence they'll hold up in our cold storage setups.
