حلقات O-Ring من Viton FKM بقطر مقطع 0.139" وقطر داخلي 3.359" | AS568-237 | داش 237 | صلابة 75 | بني (25/عبوة)

I’ve used these in a hot oil application that hovered near 300°F and they sealed perfectly with zero swelling or hardening after a month. The 75 durometer feels firm but still seats easily, and the brown color makes them simple to spot during teardown.

These o-rings fit perfectly in my hydraulic cylinder rebuild; the Viton material handles the high operating temperatures without any issues. I appreciate that they came in a resealable pack for storing the extras.

Finally found the right size for my hydraulic system rebuild—these Viton FKM rings fit the groove perfectly at 3.359" ID. The 75 durometer feels solid but not too stiff, and they handle the high heat from my compressor without any issue. Definitely worth getting the 25-pack for the price.
