حلقات O من Viton FKM | AS568-905 | داش 905 | صلابة 90 (800 / عبوة)

These o-rings handle the heat from my compressor without any softening, and the 90 durometer keeps everything sealed tight. I've used cheaper ones before, but the Viton compound here is clearly worth it.

My hydraulic setup kept blowing standard Buna-N seals until I switched to these Viton ones, and the 90 durometer hardness really holds its shape under pressure. The -15°F to +400°F range means I don't have to worry about cold starts or hot runs. Eight hundred in a pack is plenty to keep spares on ha

I've been using these for high-temp sealing on an industrial pump, and they hold up perfectly even at 400°F. The 90 durometer gives them a firm, reliable feel that doesn't deform under pressure.
