Its purpose is to insulate the dryer from the engine bay heat. The colder the return temp to the compressor the colder the outlet temperature is at the vent. You can buy some Armaflex online, cut it to fit and glue it on or use zip ties. Your home AC return line is the one that needs to be kept insulated since it runs 24/7 in the summer. LOWES and HOME DEPOT have the material for the lines 3/4" and 1/2" in 6' lengths. Your dryer will need a much larger diameter and when you find it it will be sold in bulk and you will have enough left over to do all the cars still on the road. Or buy a 6' one and cut several pieces to fit. It will be ugly but effective.

Chuck,
The dryer should be replaced any time the A/C system is opened up, they are relatively cheap I.e., less than $50. No you don’t need the insulation wrap, a replacement dryer would most likely not come with it.

Dear Forum,
This is a trivial question about the dryer in the Pantera AC system.
Is the stock factory foam insulation over the dryer necessary if converting to R134? Mine is fifty years old and ready for retirement. Must it be replaced?
