Ok so it was kind of a normal weekend.. buddy asked me to help him program up some controls and help get some units started up on one of his job sites...

all new kit, so I get there.. vacuum poumps are whirring away, im programming the computers... then I noticed and started laughing at the newbie there who was vaccing down units where the pipes were not even brazed yet....

then he starts laughing at me and said "brazing is for old fuddy duddies".. turns out they have been using something called "HVAC super pro"...

basically they are gluing together their pipework.. and it claims to work even with 410A systems... said theyve been using it since last summer and it doesnt leak...

does this stuff actually work? i would love to use somnething like that on a job where im concerned about pipework too close to flammables..

but somehow im skeptical wioth all the expansion and contraction that copper does in a heatpump system that the "glue" would just crack...
