I was crushed.
Lightly compact thing was good because the fit tube outer diameter 6Φ, I bought the Screw diameter R R1 / 8 but was crushed deformed parts sandwiching at suddenly wrench during tightening.
Although I did not know what's a moment because it was the first time the experience was going on, it apparently as the wall thickness is too thin stiffness for pointing small until the last minute due to the small size and weight reduction has been crushed in the clamping force is not enough , normal type it sounds like there is impossible to correspond to 6Φ tube because this mini-type dihedral width is set to 10 mm for the dihedral width of the hexagonal part of a 12 mm, glasses not'm spanner in do you Tteyuu also open ring to tighten so, the glasses will not enter the portion of the tip in pushing at the time to remove the tube is slightly larger than 10 mm.
About maybe You think that it is just a matter of goods of this size, but you might want goods to those who are top priority to small and lightness towards the other, please note, to return but I bought four because of not a amount of money is going to be the rest of the three and the bad inventory.
Tube desorption with clean making is also certainty.
However, the material of the lock pin is almost no rotation of the lateral direction too grasp a firm tube seems different from the PC4-M6.
To use in modeling the head portion I think that is not suitable in the transverse direction this application for rotation is also necessary.
Is also of course the pipe was used as a place of copper fittings of the compressor, but is the problem bear how much to so is convenient thing, but 08 pressure at the touch of a button, but you can use right now of the place.
