1994 chevy rcsb AC hi pressure line seized in both ends. What to do?

[man-a-fre]

I will need alot of luck.I hope this works because i really don't want to pull the dash to put in a new evaporator because of the seized line on it.

to prevent galling in the future , I use it on o-rings and threads and mating surface
just a drop on mating surface and a couple on threads,
Nylog blue gasket and thread sealant
made for refrigeration work
every thing will assemble sooooo smoothly and more important, come apart in the future

cheap about 15 bucks

Heat that nut up , penetrating oil then heat it again and put your wrench to it
when it stops turning, remove wrench and heat up again and turn some more
as it cools the aluminum nut will shrink

Dual AC orifice on Vortec is in the middle of the line just behind the rad support. Near right front of engine.
