حلقة O من Viton FKM | CS 0.103 بوصة × ID 0.361 بوصة | AS568-110 | Dash 110 | حلقة X | 70 صلابة (125 / عبوة)

I was worried about the high-temp rating, but since these handle up to 400°F they've held up perfectly in my compressor setup. The 70 durometer is firm enough that they don't squish out under pressure, and the bag of 125 means I won't need to reorder for a long time.

The 0.361" ID fit perfectly on my hydraulic cylinder, and the 70 durometer is firm enough to handle the pressure without deforming. I've been running them at 350°F for a week with no leaks at all.

I needed a high-temp seal for a steam valve at work, and these Viton FKM rings have held up perfectly under 350°F cycles. Exactly the 0.361" ID I measured for, and the 70 durometer gives just the right squeeze.
