Re: Forgot more than I know

If you go to a different orifice tube (OT) then "buying an orifice tube that comes in a FORD box" is the only way. Whether the OT is all covered with crud will be interesting. There is a small filter screen on it to collect junk before the actual orifice. Superheat and subcooling are not e...

Re: Forgot more than I know

When all the other components were replaced after the compressor died, ( the metering device you are referring to is called an orifice tube, it is a fixed orifice), it would have been a really good plan to have flushed the evap and hoses. An exploded compressor tends to shower the rest of the system...

Re: 1993 Dodge Cummins AC troubles

Call Tim and see what he might be able to get. Direct conversation usually more helpful than going back and forth on a forum. He is a good guy.

Re: High Pres Line Splice

You are correct, compression fittings are nearly useless. Flare fittings are used on copper tubing in residential and commercial HVAC all the time. Have refitted copper on a commercial freezer box (-40°) using flare, as was the original. Use Nylog on the flare, and be sure they are tight. However, c...

Re: A BIG THANK YOU !!

Done. Ordered. Not what you see hanging on the walls at Johnstone and Baker.

I'm on a couple of HVAC forums and have seen how they set up their trees. Never a word about black hoses, tho.

My full time job is with my nephew restoring vintage vehicles, and not stuff like a tri-5 chevy. Earlie...
