The McAlpine WC-CON8V is a toilet connector designed for use in plumbing installations. It has a 97-107mm inlet size and a 4"/110mm outlet size, with a 90 bend that allows for easy installation in tight spaces.

This allows for the connection of a soil and vent pipe, which helps to ensure that the waste from the toilet is properly ventilated and disposed of. Overall, the McAlpine WC-CON8V is a high-quality toilet connector that is designed to provide reliable and efficient performance in a wide range of plumbing installations.
