The McAlpine WC-F18R is a flexible WC (water closet) connector used to connect a toilet pan to a soil pipe. It has a 97-107mm inlet diameter and a 4"/110mm outlet diameter, which means it can fit a range of different toilet pans and soil pipes. The flexible design of the WC-F18R allows it to be easily adjusted and maneuvered to fit around obstacles, making it ideal for use in tight spaces or where the position of the toilet pan is not directly above the soil pipe. The connector is made from a high-quality, durable material that is resistant to chemicals and ultraviolet (UV) radiation, ensuring a long lifespan. It's important to ensure that the McAlpine WC-F18R is installed correctly to prevent any leaks or damage.
