McAlpine WC-F26SV Long Flexible Pan Connector with Vent Boss for 90mm Cast Iron

Features

The McAlpine WC-F26SV simplifies complex toilet installations involving 90mm (3½”) cast iron soil pipes. This long-reach flexible connector includes an integrated 1¼” universal vent boss. You can easily connect an air admittance valve or extra venting pipework to this boss. Additionally, we include a blanking cap to seal the boss if you do not need it. Since McAlpine manufactures this unit from durable polypropylene, it offers a reliable, long-term solution. It also fits the 3½”/90mm internal diameter of cast iron soil pipes, making it an essential tool for difficult bathroom layouts.

• Integrated Vent Boss: The 1¼” universal vent boss assists systems that require extra air intake or ventilation.
• Convenient Blanking Cap: You can easily seal the boss using the supplied blanking cap whenever it remains unused.
• Flexible Adjustability: This unit provides an effective length of 180–380mm. Consequently, it helps you bridge large gaps between the pan and the cast iron stack.
• Cast Iron Compatibility: The outlet specifically fits the 3½”/90mm internal diameter of cast iron soil pipe systems.
• Hygienic Design: Independent tests confirm that the bellows design prevents sediment build-up. Therefore, you receive consistent waste flow performance.

Details

Toilet installations often reveal poor ventilation in older cast iron soil systems. This lack of air often causes gurgling sounds, slow drainage, or trapped odors. Usually, plumbers find that retrofitting a vent pipe into a finished bathroom requires destructive work like opening walls.

The McAlpine WC-F26SV eliminates these difficulties. Because it integrates a vent boss directly into the connector, you gain an immediate access point for ventilation. Therefore, you solve both long-distance connection and system venting issues in one efficient step. Ultimately, your bathroom plumbing will operate quietly and effectively.
