    Trying to make a stubby gauge

    Hello everyone,

    I bought some parts to try and construct my own stubby gauges. After hooking it up to the system, refrigerant was leaking out of the middle part of the 1/4-1/4 union. I know this is a simple thing to do, but its the first time Ive ever tried making a stubby gauge. Ive included a picture here of one of the stubby gauges put together, with the parts and leak location labeled (didn't have the union tightened all the way for this picture).

    The gauge came with its threads already taped. The threads at the end near the valve were not taped. Is that the problem? Hopefully one of you has put these together before and can suggest a quick fix. Thanks!

    yes its leaking because the gauge connection is a regular connection and the union your using is flare x flare, so you need to buy a couple more fittings . ill try and take apic of mine and upload it. i did the same thing.

    You might try a new quarter inch flare coupling

    To many fittings in my book. I never need a hose, just 1 of these and 90 core depressor if needed.

    There are cases where a hose is nice.

    I used to have stubbies made with an 1/8" pipe female coupling and a 1/8" x 1/4" male flare adaptor. Screw a hose on it and go.


    Those "ice machine fittings" which is what we call them, are nice. I've got a mess of them screwed onto transducers for a monitoring setup that I built.

    You should get a pipe fitter to do it for you. Lol.
    You need to put the phone down and get back to work!

    As stated above, you need a 1/4" female x 1/4" flare quick coupler. The 1/4" npt threads on the guage are not made to screw into that 1/4" flare coupling.You can then decide whether or not to use the hose and valve.

    I tried it with the 1/4 inch before but the 1/4 inch tube is so delicate it doesn't take much to bend it and break it. one thing I did to overcome this was cut a 3/4 PVC about 4 inches long and fit it over the 1/4 tube and flare nuts before tightening. the pvc kinda protects the connection from bending and breaking. but it doesn't stop it from leaking from the flare nuts ect.

    They make 1/4" flare couplings without the copper tubing.

    They make a much sturdier setup.
