I have in the past replaced these with either a R134a or R413a pot.

You have to decrease the length of the capillary though.

tks for your sugestion chillin out but the costumer have his own compressor with mineral oil working with r12 that's why i chose r 409....his budget is not enough for a new compressor with r134....i will try to cut from tube cap 20% to see how will work....
tks for your replay
