حلقات O من السيليكون | AS568-418 | داش 418 | متوافقة مع FDA | صلابة 70 | أحمر (11/عبوة)

Used one to replace a gasket in a hot water valve and it sealed perfectly right away. The 70 durometer feels firm enough to handle the pressure without being too stiff to seat.

The red silicone feels much more durable than the cheap black ones I’d used before, and the 70 durometer is exactly right for sealing my water filter housing. I was glad to see the package included 11 rings—just enough for the job with a couple of spares.

The high-temp rating was the main reason I grabbed these, and they fit perfectly on my brewing setup’s tri-clamp connections. The red color also makes them easy to spot during disassembly.
