I purchased it based on the length and the thickness for painting. The use was wrong, or the spiral was too hard. It does not grow at all. It might be good for a heavy impact wrench, but it was not suitable for painting that moves the arm.
It is not attached with the fitting that converts the G1 / 4 female screw to the PT1 / 4 male thread in the product image. Since there is no way to use it, remove the female screw and use a resin urethane hose attachment coupler. I do not write that the fitting has a fitting in the item description, which is really it?
