Reducer fittings in drainage systems are purpose-made adaptors that facilitate a smooth transition between pipes of differing diameters. Rather than forcing incompatible pipes together—risking structural failure—these fittings guarantee a watertight connection, especially during retrofitting projects where pipe sizes may vary.
