new 134a cans

[Cornbinder89]

Without knowing the very basics of the system (what a compressor is and where it is located) I have to say you are way in over your head. I am not saying...

The reason I go with small cans, is I use so little at a time, I hate to have a 30 lb keg open , if the valve leaks a little I could end up getting one...

I call my test light an "optical voltmeter". There are time you WANT to load the circuit you are testing. I guess I was "asleep at the...

Has anyone but me fallen victim to the latest A/C change? It seams that the old 134a cans that were tapped by piercing the neck are yesterdays news, they...

Natural gas stays gasous (at sane pressures) to well below -100F, LNG is NG that is pressurized to the point it will liquefy, several thousand psi....

[Cornbinder89]

Propane is liquid at atmosphic at -44, but the tank pressure drops under 10 psi when the temps dip below 0. That's assuming its pure propane and not...

Came yesterday and looks like the one I put in last spring, Still made in China for Santech, but can see no difference. The place I mail ordered from...

[Cornbinder89]

Could be any of the above. Should be here today so I can put my eyes on it. I went to my last order, and just hit the "reorder" button, so I...

The 1st multi flow large condenser I bought was a Red Dot unit (MEI) cost around $240, the next one I bought was Omega (same dimensions/ type) was around...
