    Question Not sure what it's called....

    Ok, so I saw a video the other day and a guy had a filter-like thing on his gauges. I cannot find it now to show a picture, but it was brass, about 3 inches long, hooked in between the manifold and the hose. On this in particular gauge, it was on the liquid/high side and was screwed in directly to the manifold.

    I am trying to describe this to the best of my ability. Hopefully one of you guys can understand what I'm talking about and let me know what it is, what it does, and if I should be using one.

    Thanks for your time in reading this and your reply.

    Is this it?

    We use these on our manifolds when working on a burnout or heavy moisture system. It keeps some of the debris out of the manifold and recovery machine. There are other ways to do it, but these are small and easy to carry. If we are pulling down a large system, we have filter driers rigged up to protect the equipment.

    Maybe it could be a liquid feed device thing, I have one if you want to see a picture, where the tech can charge into his guage liquid which evaps into a gas going into the unit.

    Typically, they are located on the low side though for charging while the system is running.

    a liquid charger?

    or a filter drier?

    would be helpful to know which one, either is a possibility.

    if it's a liquid charger, you can spend that money elsewhere

    well, that would be a good investment for inexperienced guys. IMO

    But an experienced tech should be able to throttle his manifold to achieve the same thing.

    and then there's heat pumps... doesn't matter much if you've got a suction accumulator lol

    I have one. I've used if maybe 3 times over the past 30 years. They do work but I've learned to crack my low side charging port to do the same thing. If you have money to spare and want to experinment I'd get one. Other than that I would not.

    I've used it to pump liquid in big systems using my Appion machine. Stops the machine from jumping all over. Really not for much else though.

    If you are charging VERY small units (charge measured in ounces) the Kwik charge can help to meter the charge more accurately.

    That said, I have one riding in the drawer in the back of the van. I used it once to see what it did and how fast it flowed refrigerant.

    It has been in the drawer ever since.

    a quick charge, and a liquid charger are two separate things
