    Loctite 648 is what the manual calls for .

    I was told or read that it is the retaining compound not the threads that holds the tube in as well as seals them.

    The threads are very fine and if removing, cleaning and reusing a tube , there is a fair amount of play. That 648 makes up for that and it sure holds and seals well .

    The tube came apart easily using a digital heat gun at 600 degrees for about 4 minutes. It cooled quickly so I had to reapply heat. I am now trying to pre fit the hoses and the spider which when moved doesn't lend itself to straight run hose installation. "conti"hose is stiff and 17mm is non existent in the U.S. Thanks for the info on the locktite. Progress is slow but it is progress.

    As it appears, most of your sealant was on the outer threads. Wicked In.
    Clean them up well or they will not go back together.
    You can get the remainder off with a wire brush.

    Be careful when reassembling, They cross-thread and bind up for any excuse.
    Lacquer thinner or similar helps to act as a temporary evaporating lubricant.

    5/8" hose will fit tightly. Once it is in place the only way to remove it is to cut it off.
    Be sure the hose clamps are on the hose beforehand.
    Once they are installed more than 3-5 minutes, they are permanent.

    Hi Jay,
    If you need to make a bend and the 17mm hose gets a flat spot you can use a spring on the inside to keep the diameter round and full flow. This is done with several aircraft MFGs with the 17mm coolant hose. I also see springs in oil hose to keep them open where they bend. Seems to work very well.
