    Primers

    Okay Folks, got a couple of questions for those far more knowledgeable than I regarding primers (manual, either Kohler or Essex).
    1. How doesone attach a primer line to the primer shown in this photo?Click image for larger version.

    2. If one needs to use a compression sleeve and nut, are there any hints / tips/ tricks to doing so?
    I have gone to Piper Drawings 11382, 12458 (specifically,Section E-E) and Tech Order AN 01-140DEA-2, pages 69 and 70 (the erection manual for the L-21). All of these have been helpful, but not directly addressing my specific questions.
    Just as an FYI for those who might flounder around with these things, like me, in the future, there are at least three methods of attachment of primer lines to the primer (isn’t it wonderful to have choices).Click image for larger version.

    The are AN fittings like the blue nuts you have pictured, there are nut and ferrules with AN numbers sold by Spruce and others and there are the are the automotive/hardware store type ferrule/nut. They all have different threads.

    These are the automotive or weatherhead style compression nuts and sleeves that Steve mentioned. They might work for that reverse flare type you have there. Univair shows them but I know NAPA also carries them at some of the bigger locations.
