حلقات O من Viton FKM | AS568-162 | داش 162 | صلابة 75 | بني (16/عبوة)

These o-rings held up perfectly in an application where the temperature fluctuates between freezing and near 400°F. The brown color makes them easy to spot during assembly, and the 75 durometer feels just right for a tight seal without being too stiff.

I needed some o-rings that could hold up to heat and chemicals, and these Viton ones fit the bill perfectly—the 75 durometer feels just right for my application. They sealed tight on a hydraulic fitting with no leaks so far, and the -15°F to +400°F range gives me confidence.

Used these on a steam valve that sees temps around 350°F and they haven't leaked a drop after a month of cycling. The brown color made them easy to spot against the black housing during assembly.
