I assume that the pipe/line is aluminum. Here are several links to some
information that may help you out. Trying to solder/braze the aluminum
line is not really recommended because it is easy to burn through or
weaken the tubing with heat.
An aluminum brazing rod that may be safe to use:
Aluminum repair epoxies for evaporators and tubing:
The key to the use of epoxy for the repair is careful preparation.
It might hold for quite awhile , especially if you put a double layer
on the leak with time for the first layer to setup real good . The
preparation of the spot to be worked on is very very important ---
sand it down real well then clean it with rubbing alchohol and let
dry. Apply the first layer reasonably thick then let dry for a good
1.5 days before applying a second layer and waiting another 1.5 days
before recharging the system. If that doesnt work, then try a
product from AutoZone which is used to cold weld exhaust
manifolds...cant remember the name of it right off hand but it has the
word 'Thermo' something in it ; I fixed an exhaust manifold crack
with this stuff and it held well. Only about $6.
