Description
The offset extension piece 10mm is used to extend a rigid WC pan connector while adding a small 10mm offset. It is a practical fitting for toilet installations where the pan connector needs extra reach or slight adjustment to line up with the soil pipe.
This McAlpine WC-EXTC extension piece has a 4″/110mm outlet and is designed for use with compatible McAlpine rigid WC connectors. The adjustable length and 10mm offset help with awkward toilet waste connections where the existing pipework is slightly out of position.
Made from polypropylene, this white WC connector extension is suitable for plumbers, builders and bathroom installers working on toilet replacements, refurbishment projects and WC waste pipe connections.

Fitting an Offset Extension Piece
Before fitting, check that the WC connector, pan outlet and receiving soil pipe are clean, sound and free from debris. A clean connection helps the seals sit correctly and reduces the risk of leaks.
Fit the offset extension piece to the compatible rigid WC connector, then connect the 4″/110mm outlet into the receiving soil pipe. Make sure the fitting sits naturally without twisting, strain or poor alignment once the toilet pan is positioned.
10mm Offset Extension Piece 110mm Version
This offset extension piece is the 4″/110mm WC-EXTC version. It is intended for WC connector installations where a small 10mm offset and adjustable extension are required.
Before ordering, check whether the installation needs the 4″/110mm version or a different outlet size. If a standard straight extension is required with no offset, a straight WC extension piece may be more suitable.
