    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?

    Yes
    Signature on hold. Trying to find a real Jefferson quote I like. Others here have bogus Jefferson quotes too.

    I always keep the suction pressure from the last sytem I worked on in my hoses and manifold; I drain the high side back into the system through the low side so whatever that pressure is stays in the gauges.

    As far as bleding the 6" extension, I use valve core depressors a lot of the time, so when I attach the hose to the depressor I can bled some of the pressure from the gauges at the depressor. This also saves freon burns in those tight places.

    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.
