o rings

Hey guys I was wondering if anyone knew where I could find the o rings for a dead rabbit v2. Or maybe even know the size of them so i could buy some replacements? The orings on this thing have shitted out on me time and time again.

I had a few SXK Kayfun V5 clones in rotation for a while now. At first I had a really hard time cleaning them (usual drill "a few cycles in ultrasonic, build and go vape" resulted in the most awful taste ever), but after some rigorous scrubbing, boiling etc everything went to normal. At least so...
