    low loss adapter

    need help with finding a low loss fitting for the high side of my gauges. the manifold i bought did not come with low loss fittings on the hoses so i need an adapter. teacher told us we could find them for $10-$15 but so far all I see online is $40-$50. anyone know a good place to find this piece? thanks in advance.

    I agree with ST.

    I've used low loss fittings for years, and always silently cussed them when they leaked, blew out an o-ring or wouldn't flow or wouldn't depress the schraeder, or when the internals came loose and they wouldn't turn.

    Need I go on?

    My next set of hoses will be a set with ball valve ends.

    I agree with the ball valves, I used the low loss fittings for the 1st few years (didn't know better), but now I rarely ever use em.

    I have a couple in my van still, hardly ever use them though.

    I also have a couple of these too, and man these lil things are handy!

    Those Yellow Jacket hoses with the ball valves permanently attached are pretty pricey. Has anyone had luck with the Yellow Jacket ball valves that just attach to your existing hoses?

    I have ball valves installed on my manifold and I carry 1/4" flare ball valves in my bag.

    They are YJs and they are quite reliable.

    Had one give me quite a shock the other day. I put it away closed, pulled it back out some time later, opened it and got a shot of liquid refrigerant.

    Same here. Get the YJ valves. I only use one on the liquid/high hose. Easy to dump the liquid hose back into the Low side through the gauges (and not dump 2 or 3 Oz. of gas to atmosphere).
    Yes, I know I Shouldn't But I Just Can't Help Myself...

    Yellow jacket make 6" adaptors that go on the end of your current hoses. I llike them better than the hoses with the valves built in. The reason for this is I have had a problem with the valves leaking under a vacuum, you don't notice it under pressure. If the valves are built into the hoses and start leaking under vacuum you can't pull a deep enough vacuum. With the extentions if they start leaking under vacuum, you can remove the extentions when you pull a vacuum and then reinstall after the vacuum is braoken.

    Are these universal for any hoses regardless of if the manifold is for 22 or 410?

    Yes to the best of my knowledge.

    The problem with the YJ 6" hoses with ball valves is that the hose is permanently connected to the ball valve.
    There is no way to purge the air out of the 6" hose, so you have to purge the entire hose back to the manifold to get the air out.

    NRP makes a kit that has three 6" hoses and ball valves with standard 1/4" flare hose fittings. Using them, if you keep a little pressure in your manifold and hoses all the time, all you have to do when you hook up to a system is purge the air out of the short 6" hoses.
    Even with that setup, I still use a low loss fitting on my high side hose.
    I've been using NRP low loss fittings for a number of years and haven't had anywhere near the problems with them I used to have with the YJ fittings.

    I don't like the hoses with ball valves made onto the end because there are a lot of systems out there that you would need additional adapters to connect to, due to the position of the service valves.

    Also, YJ PlusII charging hoses are garbage...
    If more government is the answer, then it's a really stupid question.
