    Liquid passed thru sometimes.

    Liquid passed thru sometimes.
    Not always as expected. When your low side is very low, you may see Liquid passed thru. I tried both attach blue adapter to manifold and attach to tank.You really need manifold with observation window.

    Couldn't be happier with this device. It's simple, and does what it's intended to do. Bought one for each of my manifolds and always have them on when I expect that I'll need to charge or add to a system.

    4.0 out of 5 stars Goes on cylinder....not on gauge set.
    Reviewed in the United States on September 30, 2018
    Verified Purchase
    I threaded this onto the gauges I have, and it bottomed out before making a good seal. On the refrigerant cylinder there are plenty of threads and it seals up fine.

    So put it on the refrigerant cylinder, turn cylinder upside down and proceed. I opened (not cracked, but opened) the low side valve, it spikes up about 75 psi. However, over the next three seconds it drops to about 20 psi above the low side pressure level. It then stays about 20 psi above the low side pressure until you are done feeding it refrigerant. Definitely faster than not using the adapter. Simpler too.

    So for those saying it takes longer, I'm not sure what to think. Maybe you barely crack the low side valve on the gauge set and leave it there when you see the initial pressure spike? Maybe never opening the low side valve?

    For those saying it is unnecessary you are correct. But it isn't expensive. It will prevent an inexperienced person making a costly mistake. It saves time and makes the process simpler. For $11 that doesn't seem like a bad deal to me. I've not tried the other similar devices so I can't compare them. This one works. Yes it is an aluminum fitting with o-ring and a plate that has a tiny hole in it. Maybe less than 1/32nd of an inch. But it does what it claims.

    Highly recommended. Docking one star on the rating because they should have instructions indicating it needs to go on the refrigerant cylinder.

    How can one review such a simple device. It's male and female flare connectors joined by a little hole so that if one puts the female on the liquid side side of a recovery tank or takes liquid from a supply tank it will flash to gas coming out of the male side and you can charge with gas of the same composition as the liquid without worry about 'glide' in blend refrigerants. It is just what it claims to be and therefore there is no ground for complaint unless someone doesn't like the color.

    Reviewed in the United States on May 8, 2021

    To get the best mixture of whatever refrigerant you are introducing into a condenser, turning the canister upside down and liquid charging is best and this tool allowing the liquid to be flashed into a gas is perfect.

    This liquid to vapor charging adapter works as it's intended to. Great product and a must have for HVAC system charging especially for r410a suction line liquid charging so to not saturate the compressor oil with refrigerant and displace the oil into the linesets which would shorten the life of the compressor. Yellow Jacket is an industry leading manufacturer of HVACR equipment and tools.

    Works exactly as described. This is attached to the refrigerant tank valve and then in turn attached to your 1/4” manifold hose. Do not listen to the other reviews that say it leaks when attached directly to a manifold, it was never designed to attach to a manifold, only to a tank fitting... this is designed to charge a zeotropic liquid directly into the suction line without fear of slugging the compressor. If you don’t understand why you would do that then you probably shouldn’t be attempting to charge a system.
    Great value for the money.
