Questions about this item

Should I choose the 4300-50 tool or the 2RZW7 and 2RZW8 kits?

The 4300-50 is the flushing tool designed to work with the 2RZW7 and 2RZW8 flush kits; you need the tool plus a compatible kit to clean the lines.

What does the 410 figure mean for my R410A conversion job?

The tool is listed for use in R410 conversions, so it helps flush existing line sets when switching to R410A refrigerant after a compressor burnout.
