Size o-ring, fuel screw


Does somebody know the size of the o-ring that sit on the fuelscrew?

My bike is a CRF 250, but i think everybody have same size

I'm not sure what size they are. What bike do you have? Do you know what carb is on it? You can order a fuel screw + spring o-rings for your bike/carb.
