    Frown I dare you, post one of yours!

    Ok, so I did this... why? I was replacing B-I-L's compressor in Tucson and thought to myself that I should not heat the check valve on the exit port of the Copeland scroll compressor using my swirl jet torch... After all it was 110F in the shade that day. I didn't bring the oxy/acetylene rig with the number 0 torch tip that does such pinpoint precision brazing. Sooooo, I used the purple stuff in my tool bag to connect the high pressure tubing. Then when I went to Johnstone a couple of days later I noticed that their stuff was RED!!! not PURPLE!!! The stuff in my tool bag was old and it lasted about a week before this photo arrived on my cell phone from upset B-I-L. I hurried back down to Tucson with the right torch kit and some tubing and a flare tool and twelve pounds of R22 and some oil to (fit, braze, leak test, evac, charge) make things right.

    This stuff, and I've used it with fantastic results on several units that I installed (compressors) in 2009. The problem was with using it in 2010 when it had been in my truck tool bag for about 8 months too long.

    How old are you? I've been doing HVAC repairs for 35 years.

    i have been in the business for over 20 years...i don't use glue. i braze so i didn't know what it was. i have heard of it, but it seemed a little too 'home depot/kindergarten' for me. i know what color it is now...red is new...purple is old. thanks!

    i love this line from their website: NOTE: The I. D. of couplings and fittings must be 0.010 inch larger than the O. D. of the tubing being bonded for a proper bond.

    i am sure the product works ok on brand new, never-been-used-before type of copper but i wonder how well it works in the field where there is a little bit of oil you don't see or some debris...stuff like that.

    doing it that long and still admit to using "purple stuff" on a scroll discharge line????????

    i have been at it for over 40 years and would not even think of gluing a discharge line together.

    Then you ought to know better than to use snake oil.

    The chemical bond from this stuff is incredible, but the instructions are weird. You must use COARSE 60 GRIT sandpaper (provided) to rough the pipe, and do not wipe off the sanding dust. Then when you apply the red "glue" you wet BOTH surfaces because if you don't the stuff sets up so fast on insertion that the joint will be "cold" (not enough spreading/flowing). The copper dust is what catalyzes the reaction and it gets HOT. A slight twist is advised if possible, most likely you won't be able to go more than 15 degrees before it LOCKS. You must wait 12 minutes to reach 850psi strength (or to pressurize system), but I was evacuating within 5 minutes of application and opening the precharged condenser unit valves by 20 minutes as soon as 500 microns was pulled and stable on the lineset. This is Arizona and there was unmeasurable relative humidity (seriously we are that dry) at this install, so vacuum is very fast on a 5 CFM 2-stage pump.

    If I were doing daily work on locations where I routinely swap compressors or filters, I'd use this stuff. The issue I have is that I do much more PM and service between compressor change-outs. And the product was getting too old in my truck from the high summer heat (140 F in the truck just about all the time when parked).

    Here's some of the manufacturer's information and a video http://www.youtube.com/share_popup?v=U4Jk0oH2Ijo

    Bought some Friday and it is purple straight out of bottle. Do not use on soft copper. I use it for copper drain lines on RTUs. So so results on refrigerant lines probably due to me and not product.

    drain lines fine.

    I've seen this product before.

    I will openly say this:

    If you have to use a solvent bond for a refrigerant circuit you are either 2 things. Extremely inexperienced and you should not be in your own van, or your a hack.

    Either one, your call.

    I've whipped out my turbo torch and thrown fire up in finished walls, brazed in compressors, whatever. I've only been in the trade for 8 years, never had an uncontrolled fire.

    I don't have a problem with someone using it for a drain line. Thats just a speed thing for non-pressurized piping, no harm there.
