ok i got a mangon hrc hydraulic pistion the leaks at the front.
i opend it up and the little weird looking oring is torn. the o-ring is brown
and it has a small spring that sits around to opening that the piston slides through. what is the seal called? ive seen them on my old ford escort. and it
seem that the only thing wrong with the piston. i can't get a picture it's put together and on the excavator. i'm thinking this is not a one off part so if anyone know what thats called or where to get them let me know .

if your lucky it will be a standard sized "ORV" numbered oring


Measure the cross section, OD and ID

Most Hyd rams have a dust seal,fluid seal, guide rings, and du bushing

Some simple versions just have a single o ring to seal in the fluid.

I rebuilt many of this things over the years
