    Uniweld Nitrogen Flow Indicator

    Anyone using nitrogen flow indicators while brazing? I'm inclined to think its a good idea.

    Is the metering tube on top glass or plastic? (Uniweld) I asked @ my local JS typical answer ( Not Sure).

    Thanks for any info. Jay Parker

    Its glass and I highly recommend using one. Very easy to dial in a low psi for brazing.

    I use a needle valve on the regulator outlet. Thought about buying the Turbo Torch flowmeter.

    The Turbo Torch One is the one I am going with. It is $40 at our carrier supplier in scarbrough. I seen it at the Trade show its a solid piece made to last but like any gauge can be broken.

    How much is the uniweld piece going for?

    Yes its a very good idea. Reason why, click here http://www.youtube.com/watch?v=3uP-eb8Zz08&feature=autoplay&list=ULe26dkmA_CfY&lf=mfu _in_order&playnext=1
    There is an inner tube that reads the measurments and the outer protective sleeve, they are both plastic. Johnstone Supply has them on sale right now, only for the month of april I think.
