The Polypipe MU315
is a 50mm 92.5-degree cross tee fitting for a solvent weld waste system. This fitting is used to create a four-way junction or a "cross" connection in a waste pipe run, where two branch pipes join a main pipe system. The 92.5-degree angle ensures optimal flow and integration into standard building layouts.
