حلقات O من السيليكون 0.139" CS × 0.921" ID | AS568-213 | داش 213 | متوافقة مع FDA | صلابة 70 | أحمر (200 / عبوة)

These fit perfectly in my espresso machine's brew head and the high temp rating gives me peace of mind. They're a bit stiffer than the stock ones but seal way better and haven't deformed after dozens of back-to-back shots.

The red color makes them easy to spot during assembly, and the 70 durometer hardness feels just right for a snug fit. I've used them in a high-temp application around 400°F and they haven't degraded at all after several weeks.

I needed heat-resistant seals for a sous vide project and these o-rings have handled the high temps without any deformation. The 70 durometer gives them a sturdy feel that other softer rings lack.
