McAlpine WC-BP1 90mm x 110mm Boss Pipe Connector – WC to Soil Pipe Adapter with 1½" Universal Boss

The McAlpine WC-BP1 90mm x 110mm Boss Pipe Connector (EAN: 5036484016324) is a versatile WC connection fitting designed to link 90mm toilet pan connector spigots directly into 110mm soil pipe systems, while also offering a 1½" universal boss for connecting additional waste appliances like condensate pipes, basin traps, or washing machines.

The WC-BP1 features a secure 90mm 'O' ring socket for the WC pan connector outlet and a finned spigot end that pushes directly into 110mm cast iron, plastic, or clay soil pipe. The integrated 1½" boss includes a blanking plug, allowing it to be used only when required. This makes it an ideal solution for installers needing a clean, adaptable connection that supports future plumbing flexibility.
