حلقات O من السيليكون | AS568-440 | داش 440 | متوافقة مع FDA | صلابة 70 | أحمر (10/عبوة)

These have become my go-to for high-temp seals after swapping out a few worn ones on a hot water valve. The red color makes them easy to spot during assembly, and they held up fine in the steam without swelling. Exactly the 70 durometer feel I was after for a snug fit.

Used these to rebuild a pressure regulator on my espresso machine — the 70 durometer feels noticeably sturdier than the junk generic rings I had before. The red color also makes them easy to spot against the brass fittings.

These fit perfectly on my brewing kettle's thermometer port; the 70 durometer feels firm but seals well. Nice to finally have a red color that stands out during cleanup.
