I brazed that bitch up, it holds a ton of nitrous LMAO......... Just FYI, If your looking for a leak on your house A/C. nitrous line screws rite on to the freon fittings..... Works like a champ for finding leaks in your system, I found about 8 when I put about 400 psi of nitrous in the lines.

Hal, Im ready to get it sucked clean and freon added for the last time....... thank god

I have a leak on my house ac in the worst way...so you put the nitrous line on the freon fittings...put some nitrous in there...found the leaks...and then brazed the lines with residual nitrous in the lines...just want to know if it's safe...or if you did something different...I really need to get this done...lol

thanks

Hell no I pulled all the N20 out, that bitch still spewed out a fireball when I sweated some fitings apart to totally remove the "A coil". I guess it mixed with the torch I was using and made it a lil bigger flame LOLOL. Wasn't bad though, I was expecting it and it only lasted a couple secs....

I used nitrous because I didn't have nitrogen, and I was told not to use compressed air because it adds moisture to the system.

well, I can fill a nitrous bottle with nitrogen right?

once you filled the system, how did you find all the leaks?

With that much pressure in them, you could hear it....... then I went around with soapy water in a spray bottle to find the rest.

Your extra flame power was likely due to the 33% oxygen content of the N2O residual in you system. Atmospheric air is typically only 19-22% oxygen content.

The 66% nitrogen content of nitrous helps make the 33% oxygen side a little bit more stable and predictable to work with.

Thats what I figured, I know the nitrogen content is Inert, and I know nitrous by itself is not flamable, the residual pressure probably mixed with the flame when it became open to it and accelerated the burn of the acetylene torch.

I could just imagine trying to tell the A/C guy that the compressor had a Nitrous backfire and thats what caused the cover to blow off:hysterical:

does the a/c run faster with the nitrous? :)
