[R129 SL] Low Refrigerant Problem

[Baktash Taghehchian]

George,
It is a standard R134a fitting. If you go to your
local auto parts store you can buy cans of R134a and
also the fittings/hoses. Make sure you get something
with a screw type valve that you can open/close. The
ones with the trigger tend to leak and are a hassle to
use. Also, get something that comes with a pressure
guage so that you know how much refrigerant you have
in the system, since overfilling will cause problems.
