Pressure ratings for fittings that have both AVLOK® tube fitting ends and pipe thread ends are determined by the end connection with the lowest pressure rating. The Pipe End Pressure Ratings chart shown below lists pressure ratings for male and female pipe thread ends. For female and male pipe threads to have the same pressure rating in the same nominal pipe size, the female thread end would require a heavier wall thickness, resulting in the fitting being too large and bulky.
