While shipping was quick enough, the spec's on the location of the holes for mounting the valve were out. When trying to mount the valve to the cylinder it was out of alignment. By this I mean if you attached the 90 degree elbow to the tube that ran to the top of the cylinder the pipe that ran directly from the valve to the lower connection of the cylinder, that pipe was lower than the threaded fitting it was supposed to screw up to. This made it necessary to have to bend the tube running from the control valve to the top of the cylinder to need to bent a number of times to reduce it's length enough to raise the valve enough for the lower pieces to line up. Not happy with having to go through this bending process because the hole locations on your part were not where they should have been.
