I just started doing this...
I usually wear a sweat band all summer long and keep them in the truck. A few weeks back, was out of the paste & and the spray on gell ( which is very handy to use but expensive)and no spare cloth. Well the sweat band is very versatile for the brazing. Loop one end over the valve cover and around the valve and back over the cover. Works great. Was handy using it at the air handler too to protect the the expansion valve sensor (Rheem likes to wrap theirs like Fort Knox).
Just wanted to pass that on. I've been brazing with the cheapest stuff on the market for over 20 years. PhosCopper 0% by Harris. It works. And a couple of years back, Copeland cast their approval of it, so that sealed the deal, finally. Anyone else out there use it?
i use stabite all the time great stuff
every once and a while i braze just for ships and gigles
always braze in compressors just dont want to take any chances there
basic stuff man
remome valve core, add oil into orifice, wet rag (if you have one) ,and braze. Quick and easy use oil from pump if your too lazy to carry it. Brazing is tecnnique.
StayBrite#8 : Practice practice practice.
Don't EVEN try a reversing valve or such until you
get a good feel for how #8 flows. I replaced a
RV last week that had a big ol' gob of #8 in it.
Works just fine, you just need to be a master of
the flame to use it liberally.
