حلقات O-Ring Aflas مقاس 0.139" CS × 0.734" ID | AS568-210 | داش 210 | صلابة 80 (25 / عبوة)

Put them on a high-temp compressor valve that cycles daily, and after three months they still look brand new with no swelling or cracks. The 80 durometer feels firm enough to hold a good seal without being impossible to install.

I’ve run these Aflas rings in a 400°F sealing application for two weeks straight with zero leaks, and the 80 durometer hardness held its shape perfectly under constant compression. The -10°F to 450°F range is no joke, they stayed flexible even when my system chilled down overnight.

These exact-size rings were dead on for the -210 spec, and the 80 durometer feels reassuringly firm. I’m running them in a hydraulic clamp cycling up to 400°F, and so far they’ve held their shape without any hardening or leaks.
