Outlet Diameters

The outlet diameters as listed are in accordance with BS4825. The ASME specification, however, requires these diameters to be 0.005” (0.125mm) less in each case. An Outlet Diameter tolerance of +0.000 -0.005” has therefore been applied, so that the same fitting satisfies requirements of both specifications.
