    Default 3/16 end line connector

    I am starting to replace my 3/16 lines and I am using Leader fittings . Is it me or are the end line fittings badly designed. Every time you get line tight the lines pop out of the hook on fitting.

    2011 expanding to a Mason 2x4 with a blower increasing taps to about 200
    2011 Hurricane Irene rips thru my small sugar bush cost me to lose 20% of taps
    2014 I have reworked my lines for 2014

    I never used Leader 3/16 fittings, but I've found best results are achieved when you wrap the 3/16 around the tree and have the end line hook joint the main 3/16 around the tree at a 90 degree angle. When you try to pull the hook away from the tree trunk and the angle becomes much steeper than 90 degrees it tends to unhook.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    I have used the Lapierre "end of the line eyelet" fitting for 11 years and they work perfectly. My nephew put up 130 taps using the Leader end line fittings and you cannot tighten the line with them. They just don't work.

    You can also use a 1/4" hollow braid rope, slide the tubing into the center of the rope for 3-4" then out the side. Tie the rope to the end tree and it grips like a Chinese finger trap. Then adjust as needed and put the tap on the end. That method gives you lots of adjustment. To get the tubing threaded into the center, take a ball point pen that unscrews in the middle apart, slide the tubing into the big end of the pen point and push the tip into the rope. It is easy to get the tubing in as far as desired, then out thru the side. A couple of wraps of elec. tape just before the end of the rope helps keep the rope from unraveling

    In the past the only Leader end line fitting I've had success with is the end ring fitting. It grips well and is adjustable, but it leaves a kink in the tubing where it grips.

    Joe your right you can’t get a tight line with them and this is why I have a love hate relationship with Leader. They don’t put a lot of thought into their product development! Someone above mention their end ring fitting that works but only comes in 5/16 which means you got to start with 5/16 and than reduce it which is pain in keister!

    With the hollow core rope I use field tip off an arrow , the threaded end fits into 3/16 tubing and it's easy to push into the rope. I did a little bit of grinding on the tip to take off any edges

    They make rope splicing fids:

    https://www.amazon.com/rope-splicing...+splicing+fids

    I use leader end hooks and I push a piece of electric fence wire through a length of tubing and wrap it around the tree and twist the wire together behind the line side. I then hook the end hook over that tubing and it's straight and will hold. Not a lot different than hollow core rope.

    I just put my first spile in the end (top) of the line and go down from there. Don't see the point in having a loop end.

    I used to run hollow-core rope to make it tight and then a vacuum gauge at the top of my runs but don't bother anymore.
