حلقات O من Viton FKM | 0.139" مقطع × 9.484" قطر داخلي | AS568-274 | داش 274 | صلابة 75 | أسود (6 / عبوة)

Swapped out the old rubber ones for these Viton FKM rings and the difference in heat tolerance is night and day, especially since my setup runs hot. The 75 durometer feels firm but they seated into the groove without any struggle. At nearly nine and a half inches across, they cover the flange nicely

The 9.484" inner diameter was a perfect fit for my hydraulic cylinder, and the 75 durometer feels solid. Arrived well-packaged and works great under the hood where temps run high.

Had a tough time finding the right size for a hydraulic repair, but these matched the AS568-274 spec perfectly and sealed up tight on the first try. The Viton material holds up well under high heat, which is exactly what I needed for my application.
