    Dear hoses, please stop falling....

    So what dose everyone do for this very simple problem?

    Your hoses come unscrewed from your manifold. You don't want to tighten them to much so the oil will build constant pressure, but don't want to leave them to loose to come off.

    What do you do?

    Why not tight?
    Keeps moisture and trash out. Seems like some manifolds loosen more than others hanging. Might have to do with the angle of the hose park.

    I was always told that you'll wear out the gaskets faster?

    I kind of doubt that.
    Then why do the manifold end of the hose last so much longer?

    You might be over thinking this a little bit
    I've seen clips before if you would rather keep them loose. I'll look for a pic or draw something you can make.

    Just change the gaskets in the ends on a regular basis... and secure the fittings to the manifold as you choose.

    I use the short valve ends on my hoses... so the hoses never fail... just the fittings on the short valve hoses... When the valve fails... get a new set.

    The clips I've seen were metal like a double ended like these.
    Something like these could be screwed together back to back

    I always leave them secured to the manifold to keep them dry.

    Use hoses with PTFE seals instead of Neoprene. They last 10x longer.
    Neoprene brakes down with refrigerant and oil over time.

    Yes, they are a touch harder to install to get a good seal, but they last.

    I sympathize, I use the Teflon gaskets too, Expat.. is right.
    I use 37.5* flares, they get a better grip inside the tubular gasket. Also the JB parks , I usually have the flare cone ground off, so the YJ seal rights are not penetrated.

    I just replace my gaskets as needed. I inspect them pretty often. I do crack the hose fitting at the manifold often to vent air. I get rid of hoses periodically. If I have any doubts about a hose I toss it. Or cast it to the side to be used on a recovery machine. Nitrogen tank. Or whatever. Having Rock Solid hoses is very important to me. You have to know your manifold set is 100% good. Especially when pulling vacuum. I use the large 3/8 vacuum hose. A rubber gasket gets worn out and I can never replace it. I just can't get it out of there and get the new one in. So I end up tossing the hose. I go through a few of these hoses a year
