Toilet pan connector McAlpine HC38 — offset 40 mm, universal WC waste connection

McAlpine HC38 is a toilet pan connector designed to join a WC pan outlet to a soil or waste pipe with a 40 mm offset. The connector accommodates minor misalignment between the pan spigot and the soil stack, enabling a watertight connection where direct alignment is not possible. It is intended for use in both domestic and light commercial bathroom installations and is compatible with standard circular waste pipe diameters used for WC connections.

Advantages

The connector provides a reliable offset solution that simplifies installation when the pan outlet and soil pipe do not line up perfectly. Constructed from durable plastic, it offers resistance to common bathroom conditions and maintains a secure seal to prevent leaks and odours. Its universal design supports a range of standard WC pan outlets, reducing the need for bespoke adaptors and enabling faster fitting.

Suitable for

• Domestic bathroom toilet installations requiring a 40 mm offset
• Light commercial washrooms where alignment between pan and soil pipe is imperfect
• Renovation projects where existing soil pipe positions cannot be moved
• Situations needing a compact connector to bridge small offsets without altering pipework

Key specifications

• Offset: 40 mm
• Function: WC pan to soil/waste pipe connection
• Material type: durable plastic suitable for sanitary waste connections
• Compatibility: universal fit for standard toilet pan outlets and circular soil pipes used in typical installations
• Application: suitable for domestic and light commercial bathroom use

How to use

Ensure both the toilet pan spigot and the soil pipe are clean and free of debris. Slide the connector onto the pan outlet or soil pipe according to the orientation required for the 40 mm offset, then push the mating pipe or pan spigot fully into the connector until a secure fit is achieved. Check that seals or sockets are properly seated to form a watertight joint. If necessary, trim adjacent pipe ends to obtain the correct engagement depth and alignment. After fitting, test by flushing to confirm there are no leaks or misalignment issues.

Usage recommendations

Use appropriate sealants or solvent-weld methods only if specified for the pipe system in use; follow local plumbing codes and manufacturer's instructions for best results. Inspect the connection periodically for signs of wear or leaks, and avoid excessive axial stress on the connector by ensuring the pan and soil pipe are adequately supported.
