    Vacuum hose tree of doom

    Hey guys, I can’t believe I’m having trouble locating this as I know I’ve seen it before. Trying to find who sells a brass tee- 3/8” flare on one side to go onto the 3/8” male fitting on my vacuum pump, then up probably 4” with two 1/2” male thread fittings at the top to attach my two 1/2” appion hoses with 1/2” female fittings. I’d prefer if they (1/2”) were parallel to each other but I’m not going to nitpick.
    I’ve looked online, talked to trutechtools, Baker distributing, Ferguson, my service manager and my lead tech and I get blank stares. Appion sells something like this in their MegaFast or whatever evacuation kit, but that’s $600. Anyone? Bueller?

    You’re looking for the yellow jacket vacuum tree. I have one that came in the Appion mega flow kit. I have seen them at supply houses, but it’s been a while. Found many listed online with a quick google search.
    There are two ways to do things, Right and Again.

    I came across all of these as well in my initial search. While all of these products have a flared female end in 1/2" or 3/8", none of them have the two male thread ends in 1/2". Lots of choices if you want 1/4" or 3/8" but none I've found that will take my vacuum hoses

    Buy the YJ, and unscrew the 2) 3/8" SAE Flare x 1/4 MPT fittings and screw in two 1/2" SAE Flare by 1/4" MPT fittings. You could likely also just to United Refrigeration and find what you need in the brass fittings selections. One note, I would use leak lock red for all of the fittings, not for sealing, but because it dries and will not outgas as much in a vacuum.

    build your own... if your using CRTs even a tiny leak on the homemade rig wont matter as most working pumps will overcome it and still pull a deep vacuum. but hey, it is our(your) job to create leak free systems, how hard can it be....

    Sounds like all you need is a 1/2” flare union and a 1/2” flare tee.

    Or TTT and others sell really short 1/2” x 1/2” hoses if you want an o-ring type seal for finger tightening everything together.

    Another option would be to get a couple braze on 1/2” male flare taps, and some 1/2” tubing with a flare nut, and make your own that way.

    There are lots of ways to fry this egg. You just need to be a little more creative.

    I wanted to get a tree for my 1/2” appion hoses as well. Looked around quite a bit and even called TTT. Never found one. Let me know if you end up finding/making one.

    It's summer where I live and I got a 3 month old so I will probably just buy a 1/2" hose with 1/4 and 3/8 ends. I don't have any spare time to go making something from scratch. Seemed like a no brainer that someone must sell something like this individually, Appion I'm looking at you

    I think what the OP wants is this, and a standard 1/2” flare tee.

    I paint all the joints with imperial Liqui-vac sealer.

    the thing that irritates me with them is the crappy ball valves.
