حلقات O من السيليكون | AS568-444 | داش 444 | متوافقة مع FDA | صلابة 70 | أحمر (8 / عبوة)

The high-temp rating on these is perfect for a coffee roaster door seal I needed to replace. They slipped right into the groove and handled the 400°F heat without any softening.

Used these red silicone o-rings to replace worn seals on a hot water valve, and they held up perfectly at 200°F. The 70 durometer feels just right — firm enough to seal but still flexible to install.

Had a small leak in a high-temp application that was eating regular rubber o-rings. Popped these red 70 durometer silicone ones in and the problem's gone. They fit perfectly and feel much more durable than what I was using.
