    Refrigerant hoses

    What is the latest and greatest in hoses? My YJ ball valve hoses need replacing again, the shaft for the ball valve leaks after only 6 months

    Thinking of trying some low loss hoses.

    Stick with YJ or is there something better out there?

    Anyone have the JB Kobra low loss hoses? They look great and are a bit cheaper than YJ

    Had em for about 3 months, so far so good.
    Have been using the NRP low loss hoses and they are good too. I would stay away from the yellow jacket ones they are to big to use in tight spots. And leak to much.

    The only little problem I've had with the JB hoses are that they let a little more refer out than the NRP hosesout when screwing the hose on.. Almost like the depressed is further out. Which may be good for certain types of valve stems, like newer carrier units. Which I've had trouble with the NRP hoses depressing the valve stem enough.

    I've been using a set of NRP ball valve hoses for about a year, now.

    I've replaced seals a few times, but don't have any complaints about the hoses or valves.

    I dislike the low-loss type hose fittings whether NRP or YJ...

    Have my own made for a fraction of the cost. 6000 psi burst, stainless steel braided, rated for 28 microns vac. Talk with your local hose and fittings supplier. Parker brand 919B series hose and QC fittings. Key is to find a Parker representative with the fitting crimp machines on site, or you are paying a whole bunch more and might not be worth your while. I have 1/4 3/8 and 1/2 hoses in 1 ft, 3t and 6ft lengths for all flavors of our trade.

    Just what I have done.

    I was thinking about that but I don't have a hose supplier anywhere close.

    I guess I could call NRP and have them custom made...

    Can you list your source?
    Parker fitting series #?

    None of the Parker hose places around Dallas apparently stock anything.

    Been using Uniwelds EZ Turn low loss hoses for a couple months now and they are great. They are smaller than YJs and just a little bit bigger than JBs so they work great for me.

    I use those 8" hose ends with valves at the service end of my hoses... change them when they start to leak. Local shop sells them cheap. Less $$$ than buying a set of 6' hoses with valves.

    Quality work at a fair price with excellent customer service!

    Does any place sell just the ends?

    I can make the crimp die for my existing crimper.
