McAlpine WC-BP1 boss pipe for use with a compatible McAlpine rigid or flexible WC connector with a 4"/110mm rubber outlet seal.

The 3½"/90mm ‘O’ seal socket receives the WC connector prepared as McAlpine specifies; it is not described as a direct connection to a 90mm WC pan outlet. Check the connector and soil-pipe arrangement before ordering and follow the manufacturer’s preparation and fitting instructions.

  • Model: WC-BP1
  • Socket: 3½"/90mm ‘O’ seal
  • Finned spigot: for internal connection to 4"/110mm cast iron, plastic or clay pipe
  • Boss: 1½" universal vent boss, supplied with blanking cap
  • EAN: 5036484016324

The boss is a vent connection; do not treat it as a general inlet for an additional waste appliance.
