Flexible Drainage Adaptors & Reducers

Flexible Drainage Adaptors and Reducers offer a versatile solution for connecting pipes of different diameters. These special couplings are available in a variety of size ranges to suit most applications and are easy to install without the need for special tools or equipment.

Our Flexseal & Mission ranges of Flexible Rubber Drainage Adaptor Couplings and Drainage Pipe Reducers are designed with a stepped moulded sleeve that allows them to connect two unadopted drainage pipes together that have different outside diameters – connecting pipes with a larger diameter to pipes with a smaller diameter and vice versa. Each end of a drainage adaptor coupling or drainage reducer has a stainless-steel clamping band used to create a strong seal between the pipe and the coupler.

These simple yet effective connectors can be tightened onto pipes of different diameters using a nut driver and torque wrench, creating an airtight and watertight seal in just seconds. The robust design of Flexible rubber drainage adaptor couplings and reducers allows them to connect plastic drainage pipes to other drainage materials such as clay, concrete, stainless steel, cast iron and pitch fibre. This makes them suitable for use with both traditional and modern pipe systems.

Features & benefits

A quick and efficient way to connect pipes of different outside diameters and materials
Reliable, airtight and watertight seal
Wide variety of sizes available for a multitude of pipe diameter configurations.

Suitable applications for Adaptor Couplings and Reducers include:

housing sites
private roads
industrial sites
agriculture land

Please Note: Under current regulations, Flexible Adaptor Couplings and Reducers are prohibited for use on adopted drainage systems. Straight Connection couplings with a shear band should be used instead to ensure the connection is protected under earth loads. If a connection needs to be made between drainage pipes that have different outside diameters, combine a Shear Banded Coupling with a Flexseal Bush or Multibush.
