حلقات O من فيتون FKM | AS568-150 | داش 150 | صلابة 75 | بنية (50 / عبوة)

Finally found ones that actually hold up to the heat near my engine without hardening up. These 75 durometer Viton rings fit perfectly and the brown color makes them easy to spot during maintenance.

I needed a reliable seal for a chemical transfer pump running at 180°F, and these brown Viton o-rings have held up perfectly for two months now with no swelling. The 75 durometer feels firm but still flexible enough to seat easily in the groove.

They handle the heat from my industrial drying oven without any softening or cracking, which is exactly what I needed. The 75 durometer feels firm but not brittle, and the brown color makes them easy to spot on the workbench.
