Toilet waste offset connector McAlpine MAC4AEXS with 40 mm offset

McAlpine MAC4AEXS is a toilet waste offset connector engineered to shift the toilet outlet by 40 mm. It creates a compact, sealed connection between the WC pan and the soil pipe when the centrelines are misaligned, allowing installation without major changes to existing pipework. Designed for domestic and light commercial installations, the connector delivers a space-saving solution that maintains a reliable waste seal and reduces installation time.

Advantages

The offset connector offers a straightforward method to correct small misalignments between the toilet outlet and the soil stack while preserving a watertight connection. It combines a compact form factor with a robust sealing interface to minimise the risk of leaks and odours. Compatibility with standard 40 mm soil pipe diameters ensures easy integration into common plumbing systems. The product is suitable for use in confined spaces where slight repositioning of the pan is required without extensive alterations to floor or pipework.

Suitable for

• Domestic bathroom installations where centreline misalignment is up to 40 mm
• Light commercial washrooms with limited access or confined spaces
• Renovation projects that require repositioning a WC pan without rerouting soil pipes
• Situations where a compact, sealed connector is preferable to extended pipework

Key specifications

• Offset distance: 40 mm
• Application: toilet waste connector for WC pans
• Connection compatibility: designed for 40 mm soil pipe systems
• Seal type: integral sealed connection to prevent leaks and odours
• Suitable environments: domestic and light commercial installations
• Form factor: compact offset design for confined spaces

How to use

Position the WC pan outlet over the connector and align the offset to achieve the required 40 mm shift towards the soil pipe. Ensure mating faces are clean and free from debris before making the connection. Insert the connector into the soil pipe and seat the pan onto the connector to establish the sealed joint according to standard fitting practice. Verify alignment and engagement, then test for leaks by flushing the pan and inspecting the sealing interface. If necessary, adjust seating or reposition the pan to obtain an even, watertight connection.

Usage recommendations

Use the connector only within the specified offset range and with compatible 40 mm soil pipe systems. Confirm that the surrounding floor structure and fixing method for the WC pan allow for the offset position. Inspect seals periodically after installation and follow local plumbing codes and installation best practices.
