6” Clay to 6” Clay Adaptor

6″ Clay to 6″ Clay Adaptor is a purpose-made flexible coupling designed to join two 6-inch (150mm) clay drainage pipes quickly and reliably.

• Flexible design: Accommodates slight pipe misalignment and minor diameter variations between clay pipe manufacturers
• Suitable for: Below-ground and buried drainage applications

Applications

• Joining two sections of 6-inch clay drain pipe during new drainage installations
• Repairing or reinstating existing clay drainage runs without excavating the full pipe length

• Connecting clay pipework to inspection chambers, manholes, and septic tanks
• Replacing failed or cracked clay pipe joints in Victorian and Edwardian-era drainage networks

Why Choose This Product

The Kalsi Group 6″ Clay to 6″ Clay Adaptor offers a fast, tool-light installation that avoids the need for specialist jointing compounds or cement. The EPDM rubber body flexes to compensate for ground movement and minor misalignment — a critical advantage when working with older clay pipework that may not be perfectly aligned. Stainless steel clamp bands ensure the joint remains secure and corrosion-free for the lifetime of the drainage system. Suitable for both trade groundworkers and confident DIY installers, this adaptor represents reliable, compliant performance at a competitive price point.
