I have a Harbor Freight 1/2" air hose reel. The method for connecting it to the delivery line is not intuitive. The 3' hose whip does not have end fittings that swivel. Screwing it into the reel's female thread (7/8" x 14?) facing outward would loosen the connection at the delivery line. I cannot seem to find a swivel adapter for this. Of course Habor Freight is no help whatsoever. And the instructions that came with the reel have nothing about connecting it to a delivery line.
