    Yes.

    Then either using vacuum rated hoses or a knurled connection similar to the one in question are the options.

    Can you clarify this statement? I have never had a fitting on a unit get collapsed by the CRT due to the double o ring seal. If you mean the male end on the CRT, if that happens due to the copper flare, at least you can ream or drill out that end without loosing the vacuum in the system.

    pacnw, In all reality you should switch to vacuum rated hoses. If for no other reason than the fact that every couple of times you use the copper, you will or at least should be cutting and re-flaring the ends of the tub. Any little imperfections in the male flare will damage the flare seat on the tube and greatly increase the risk of leak on the next vacuum.

    ive dealt with this before, some "ripper and gripper" has to torque the livin sh1t out of the flair. normally no biggie if its just a flair. but this connection also has an internal, replaceable, repairable part= the shraeder core.

    over torquing the flair nut/cap will deform the flair and reduce the ID, thus no way to remove the core without drilling the gauge port, not good.


    only use o-ring caps and o-ring tools on 1/4" gauge ports with core. always...

    king valve with no core? ehh no biggie

    I use the site recommended/suggested vacuuum set up; vcrt, 3/8" black vac rated hoses, vac tree.

    I am trying to get info for our installers, they are the ones with the copper flare set up. Again, had some initial issues when I started here and this was found when we each did a unit at the same site. We had to get into their system afterwards and found this. I came to the conclusion it was their set up doing the "damage".

    Find some old charging hoses and cut the ends off of them and braze them to the quarter inch tubing..... then you can install some new core depressors and gaskets...... shouldnt damage anything any more than a regular set of charging hoses then.. I would do that using the core removal tool also....... lot better than using a freaking flare nut you have to wrench down.

    Having worked on several racks over the years and doing gas conversions I've run into many a squinched dill core inside the shraeder. Torque Magee comes onto it and it deforms the head just enough tnprevent the dill core from being able to come out. I found to have fixed it by reaming out the hole with a reamer. Lots of broken dill cores. Guy I worked from made an evacuation manifold, came on to the flares and never did that again when he went to out them back in... I too learned. Unfortunately on racks there's no shortage of flare nuts with bonnets and silicone which seems to be free reign to tighten to 100 inch lbs
