Description
Rubber Flexible Coupling for Imperial Pipe
Our Rubber Flexible Couplings for Imperial Pipe provide a quick, reliable and convenient solution for connecting drainage pipes without the need for solvent welding or specialist installation equipment.
Designed specifically for non-pressure drainage applications, these flexible rubber pipe connectors are ideal for joining compatible imperial and metric pipe sizes. They are particularly useful for pipe repairs, alterations and new drainage installations.
Each coupling is supplied complete with stainless steel worm drive clips, providing a secure mechanical connection between pipe ends. The flexible rubber construction accommodates slight pipe misalignment and differences in outside diameter, helping simplify installation where rigid fittings may not be suitable.

Important Installation Information
Not Suitable for Pressurised Systems: These rubber flexible couplings are designed exclusively for non-pressure drainage applications. They must not be used on pressurised water supply systems, pumped pressure pipelines or other applications requiring pressure-rated fittings.
Pipe Sizing: Always measure the actual outside diameter of the pipes before selecting a coupling. Imperial and metric pipe dimensions can differ, even when nominal sizes appear similar.
Installation: Ensure pipe ends are clean, correctly aligned and fully inserted into the coupling. Tighten the stainless steel worm drive clips evenly in accordance with the manufacturer's installation instructions.
