Rollguy, You bring up a good point about filtering...
it is possible .....and I highly recommend... that people put a filter between the compressor and the Condensor.... particularly so with any new Parallel flow condensors as I have read they have even smaller tubes than a regular condensor.. but either way it could save a LOT of money if the current R4 BLACK DEATH's ...
Rollguy, since you are 'here' what is the current state of your Sanden kit ?

One of the first few systems I retrofitted was on my neighbors TD. It took nearly a full quart of A/C flush solvent to get the hoses to run clean (evaporator and condenser still online) because of that "Black Death". I will try to find a photo and post it, it will blow your mind. I have not seen so much black stuff come out of a system as I did with this one. We also added a filter for extra protection. Yes I agree that a filter is a good idea when going with a P F condenser. It is not that hard to do, especially on the P F installations I do where new hoses are made anyway.

Leathermang,
Are you still running an R4? On R12?
If you are, how long has it been in and what brand is it?

Thanks,
Jeff
