After testing my R12 system, we found a leak at the compressor on the low pressure side. The actual leak is from the o'ring above the check valve. That part comes off the compressor. Does anyone know the correct size ring for that part or where I can get one? The compressor model is bosch 0140903226. I tried my local BMW but the one they gave is fat (probably not the correct term).
