حلقات O من السيليكون | AS568-461 | داش 461 | متوافقة مع FDA | صلابة 70 | أحمر (4/عبوة)

These red ones arrived well-packaged, and the 70 durometer feels just right for my application. I was surprised how easily they slipped into the groove without any binding, and the -80°F rating gives me confidence for our cold storage line.

Had a leaky valve in a hot water setup that needed something that could handle steam temps — these red 70 durometer rings fit the dash 461 groove perfectly and haven't budged after a week of daily use.

Popped these into a pressure cooker gasket and they’re holding up perfectly at 400°F. The 70 durometer is just firm enough to keep a good seal without being impossible to seat.
