    BTW your post looks just like an advertisement. Was there something new you wanted to discuss?

    I wish that the piping folks had gotten together and made ONE tool for this purpose, instead of several proprietary ones. I think it really slows down the adoption of the technology.

    Maybe when Sporlan's patent runs out in 30 years or whatever it is we can look forward to getting generic tools and fittings that cost more in line with what they are worth. Or maybe by then Sprolan (or someone else) will invent an even better version that costs even more.

    So should we wait for thirty years, or would that be an even worse idea? That is the question.

    I think for me (and probably 99% of other hvac/r techs), an acetylene torch (or oxy/acetylene) and normal 30 cent each fittings are where it's at.

    I do wish you luck though, Sporlan.

    ZoomLock vs. Brazing

    I think the heads/dies/crimpers (whatever they're called) are interchangeable between the different manufactures tools for propress??? Is zoomlock?

    The solution to all hvac problem would be to rid the world of the single worst refrigerant ever invented; R-410a. As to crimping fittings I just finished a 16 ton 30 head VRF system, can't even remember how many fittings I must have brazed, the tubing ended up behind some other mechanicals (builder was a dick). With the required 550 psi for 48 hour pressure test I had 4 leaks. I can tell you with pressing I would have had no leaks and had no need to run four, 88 lbs tanks of nitrogen and use 9 pounds of 15% rod. If the system had a more friendly refrigerant something like R-407c 550 psi would not have been the target pressure test, and I would have had no leaks with the brazing. The leaks were so small I never saw them with bubbles only the leak detector was able to pick them up. The same was true with 4 flare joints on the blower heads. My brother found one leak with bubbles and it was so infistemal I could not see it. When the leak detector when off I re-brazed or re-flared and torqued.

    That is it for me and VRF tried one and learned F that if the manufacturer does not allow press fittings.

    What happens when you use zoomlock, do a refrigerant conversion 7 years down the road (the way it's going lately) and need to change the oil and every rubber gasket on the system? Until the rubber O ring is eliminated I can't even think about anything but brazing.

    How about if the roofers have to move condensing units that are not elevated on steel structures when they redo roofs. They are not the most gentle of people when moving something.

    James, are you using soft copper tubing that comes in a roll? How about connecting to 30 year old stuff we run into all the time in homes?

    It works fine on soft copper.
