Concentric Coupling, 304 SS, 2 x 4 in

The ZORO SELECT - 4381016240 is a stainless steel concentric reducer intended for connecting pipes of different diameters with aligned centerlines. This conical pipe fitting provides an axial transition between 4 in and 2 in nominal pipe sizes within specified parameters, both with butt weld connections. Constructed from 304 stainless steel with a pipe schedule of 40, it is suitable for applications requiring minimal turbulence and pressure loss during flow area changes where centerline continuity is necessary. The fitting features a silver color finish and meets the specifications of ASTM A403, ASTM A960, ASTM B16.9, and MSS SP-43.
