矽膠O型環 | AS568-175 | Dash 175 | FDA合格 | 70硬度 | 紅色 (12/包)

These handled the high heat from my sous vide circulator without any issue, and the 70 durometer feels firm enough for a good seal. I’m glad I grabbed these as spares for my homebrew setup.

The red color makes them easy to spot in my parts bin, and the 70 durometer is pliable enough to seat easily without deforming. They've held up perfectly under hot water and steam in my homebrewing setup so far.

I needed o-rings that could handle both hot and cold without getting brittle, and these red silicone ones have a nice pliable 70 durometer that seals perfectly. They fit my valve assembly like a glove, and the FDA compliance gives me peace of mind for the application.
