      I'm happy to help, Roger! The image that you see is representative of the product only. This kit includes 10 pieces.

      Hi Roger, good question! You can use one part #21000 to cover both R-12 and R-134A, depending on which compressor you get the R-12 version will require 2 of the red ones, if the compressor is R-134A then the Green and the Red are required to make the conversion.

  • Q:

    Does this work for adapting R12 hoses to a 134 compressor?

      This is just a washer kit not an adapter kit.
