Zoomlock refrigeration press fittings

Have any of you guys been using the Zoomlock press fittings for a/c/ refrigeration systems?.... I have a good sized grocery store where I'm installing a bunch of reach ins and walk in boxes.... I would like some insight on the product .... before I make the jump to purchase it.....itll be a big time saver.... instead of brazing a thousand or so connections.... Thanks guys Paul S........ and I heard you can just buy the heads and it can be used on the Ridgid press machines.... RP200 and 340?

    The company I work for has used a lot of it. I myself have not used it yet.

    The only thing I herd was that if used with soft tubing that you can have leaks if the tubing comes off the roll and is not perfectly straight where it goes in the fitting

    One of my supply houses is stocking them. I'd use them in a heartbeat IF I knew they were as sound as a brazed or silver soldered joint. Refrigerant leaks are the worst, sneakiest things to happen and with armaflex and the crazy inaccessible places we run linesets, I'd need more faith than I have now. I'll sit this one out a few years...

    Thanks for the input guys...i think I'm going to braze this job, too many uncertainties .... I recently tested a zoomlock fitting....i pressurized it to 800 psi and it held.....but that is just a few joints... and they are not time tested.... I've made over tens of thousands propress connections in my career with a couple of failures due too poor installation ....i was in a rush and did not mark the depth of the pipe.... and in my opinion propress fittings will not leak and I believe just as good as soldering... but that's low pressure water....press fittings for high pressure gas I'm very sceptical

    Anyone old enough to remember Carrier's Compatible fitting from the '70s and '80s? If soft copper was used that wasn't perfectly round, then it would most likely leak. Use hard drawn and never have a problem. But that meant having to braze a hard drawn nipple on to the end of a soft drawn line set. So, what was the difference in doing that or just having a service valve that could be silfossed? Carrier finally wised up.

    I just don't see that much difference between that and the Zoomlook. I hope I'm wrong, but I would have more confidence in it if they'd used two O rings instead of one.

    My employer started using ZoomLock a couple years ago. We have some pretty large VRF systems that went very smoothly and haven't had any issues. We had three smaller projects that had leak issues, and all but one leak were traced to improper installion practice. If not installed with care, it is easy to damage or dislodge the gasket when inserting the pipe. Soft copper does seem a little more problematic than hard.

    We've all unrolled enough copper and felt it egged out, ng for the Zoomlock seal. I can see success with hard drawn, which rarely gets used residential. The next think is how long will the o-rings last, will they be compatible with the next generation of refrigerants? Will they withstand chemical flushing?

    Again, haven't used it myself but some I work with have. They also said the smaller sizes are more problematic.

    I have a death grip on my torch
