This Flexseal Adaptor Coupling, also known as a reducer coupling, is designed with a stepped moulded sleeve that allows it to connect unadopted drainage pipes together that have different outside diameters – connecting larger pipes to smaller pipes and vice versa. Each end has a stainless-steel clamping band used to create a strong seal between the pipe and the coupler.

One end of this drainage adaptor can be connected to a pipe with an outside diameter of between 170mm and 192mm, while the other end can be connected to a pipe with a reduced outside diameter of between 144mm and 160mm. Its robust design allows it to connect pipes of different material types too, such as plastic, concrete and clay, making it suitable for use with both traditional and modern pipe systems.

Important Note: This adaptor coupling is not suitable for use with ribbed pipe.

Product Features at a Glance:

• Made from EPDM rubber.
• Quick and easy to install.
• Stainless-steel clamps ensure a tight seal.
• Connects pipes of different outside diameters without the use of a bush.
• Suitable for use on any pipe material.
• Pressure rating of 0.6bar, 8.70psi and a jetting resistance of 180bar.
• Temperature range between -50°c to 80°c (constant)/up to 100°c (intermittent)
• Tightening Torque = 6Nm

Suitable applications for this Adaptor Coupling include housing sites, private roads, industrial sites, and agriculture land.

Manufacturer’s Advice: In October 2011, the ownership and responsibility for private sewers and lateral drains in England and Wales was transferred from the homeowner to the Water Company. Previously, any coupling could be used to make a repair under the building regulations but now, following the transfer of responsibility, repairs have to comply with WIS 4-41-01.

Under these regulations, Adaptor Couplings are prohibited for use on adopted drainage systems. SC (Straight Connection) couplings that are shear banded should be used instead, to ensure connections are protected under earth loads. If connections need to be made to pipes with different diameters, combine a Shear Banded Coupling with a Flexseal Bush or Multibush.

Flexseal Adaptor Couplings

Flexseal has been certified by the British Standards Institution (BSI) as a company of assessed capability, with a quality management system which meets the requirements of BS EN ISO 9001:2015. They are the leaders in wastewater connection innovation; utilising the most advanced methods and techniques for precision-manufactured products, all of which comply with or exceed relevant British and European standards to ensure reliability and sustainability.

Their range of Flexible Adaptor Couplings are made from three component parts - one stepped moulded EPDM rubber body, with two different diameters on each side, and two stainless steel clamp bands, which create a secure connection when tightened.

These simple yet effective connectors can be tightened onto pipes using a nut driver and torque wrench, creating a permanent airtight and watertight seal in just seconds.
