Description
The 160mm–178mm Gully Pot Outlet Adaptor (HDPE Black) is a versatile push-fit reducer that connects gully pots to standard drainage pipework. Designed for fast, secure installation, this outlet adaptor supports both 160mm and 178mm diameter pipes, making it a flexible choice for civil and construction drainage systems.
Manufactured from recycled high-density polyethylene (HDPE), the adaptor is durable, lightweight, and built to resist chemical and environmental exposure during underground use. It is black in colour, matching the standard gully pot finish, and slots directly into the base outlet of compatible pots.
This adaptor is suitable for both 450mm and 500mm gully pots and ensures secure pipe transitions without the need for custom fittings or glued joins. Whether connecting to existing pipe networks or new drainage layouts, this push-fit design saves time on site and allows easy adjustment if alignment changes are required.
With a simple stepped outlet profile, it creates a tight seal on either 160mm or 178mm drainage pipe systems, commonly used in foul and surface water setups. It can be used in driveways, highways, housing developments, and commercial groundwork projects — anywhere a gully pot transitions to buried drainage pipe.
