    SWIVEL FITTINGS ON MYdc ak 900 46081 YJ MANIFOLD MIGHT NEED GASKETS

    I have a problem with the swivel fittings on both my ak 900 heads.

    The one on the JB revolver is for service work so its not so critical as I am no evacuating with it.

    The 46081 is a different story. This is an evac manifold and the hi-side will not register less than 28.9 to 29 "hg..

    I can pull an excellent vacuum but it takes an hour and a half longer.

    Had to retire it until I get this problem resolved.





    Boss got my AKs from TTT and they sent us the swivel 90*s.


    I Leak locked the fitting cause I was going to use the 46081 for evacuation but I figured "what the hell ?". Torqued the living day lights outta both manifolds but they leaked at a measly 200 PSIG and bubbled up w/Big Blue anyway.

    I had to really wrench on both leakers to get them to stop.

    The revolver manifold with the AK is good for service work.

    The evac manual has a minute leak. It won't stop no matter how much it's tightened.

    One of the posters put a pic of the swivel fitting using a gasket.

    Maybe that is what I need stop this leak.

    My low side reading on my AK stays at 30"hg while the hi side rises very slowly.



    Any help?

    Dude.

    Save yourself a lot of headache and aggravation and lose the manifold for evacuations.

    Mo fittings, mo threads, mo joints, mo leakies.

    No brainer, IMO.

    Get a setup like this, even compared to the 46081 this is so much quicker.

    Have you zeroed in the absolute scale like is in the manual?
    Might not be a leak at all especially if both are doing the same thing.
    Might have something to do with atmospheric pressure.

    Mike I remember seeing a thread on your setup. Can you put a link to it or post a parts list? Thanks

    Re read the OP
    You are at the lowest reading on the high side.
    If the high side changes to 30" that would be a blinking out of range value.

    I made my own duplicate of a setup that slctech had on another thread. He has the materials listed in the beginning, it works awesome.

    The fitting swivel is leaking and won't stop no matter how much it's tightened.
    I am asking if any one knows where I can get and what type gasket
    could be used to solve my problem.

    you KNOW I don't use a manifold as my primary method of evac uation..

    The manifold was labor of love for me and is only used when time allows or the whim strikes me.

    It was a a project and a labor of love to put it together. I have almost a grand into the manifold with the cost of the DC,temp clamp, Appion 3/8 colored hoses and 1/2 evac hose, The YJ 46081 manifold alone was $300.oo. So I am not giving up on it.


    This manifold is no different than than the Apion Super Evac manifold. But i don't see any body complaining about Appion's manifold. My manifold uses the same size hoses and works just as well.

    My problem is one uncooperative swivel 90, not my method of evacuation.

    So if any body has a clue to the gasket please let me know. My Google search turned up nada. Even sites that had diagrams with fittings that showed gaskets being used , none of the staff knew nothing about it.
