So it's a bit tight to install the hose to my sprayer (regular 1/4" npt) but other then that seems to be well made and ok material i tried it with water pressurized at 3000psi and they works as they should. . Just be careful when you maneuver hose around not to kink it cause it will keep on doing it on the same spot. Gasket for the tip holder is not good it brakes easy. I'm Not sure about longevity cause I just used then to try my rigs after repairs.
