Since its inception in 1989, Flexseal has been at the heart of the civils and drainage sectors, playing a vital part in shaping the way contractors repair and refurbish drainage and sewer pipelines across the globe. With a 30 year reputation for supplying high quality products, Flexseal offers a service to match and operates with a spirit of innovation across all areas of the company. With a solution for any scenario, Flexseal’s coupling portfolio is vast and comes with the assurance of over 30 years of rigorous testing.
Flexseal manufactures the most extensive range of Shear Banded Couplings available in the marketplace and has revolutionised traditional pipe repair methods over the years. Flexseal shear banded couplings are specifically designed to connect and repair pipes on adopted sewer and drainage applications.
Shear banded couplings are a requirement of the UK water companies when connecting onto their assets. This requirement forms part of Water Industry Specification (WIS) 4-41-01, which outlines the requirements to connect pipes on adopted systems using only shear banded couplings.
The shear band on this range of couplings gives the connection added protection against shear loads that could cause the pipes to become mis-aligned.
Approvals
All Flexseal Standard Couplings are manufactured in accordance to ISO 9001:2015 and comply with BS EN 295-4:2013 and WIS 4-41-01, suitable for private and adopted (public) drainage and sewers.
Materials
EPDM – certified to BS EN 681:1: Elastomeric seals – Material requirements for pipe joint seals used in water and drainage applications.
1.4301 (304) Stainless Steel – certified to BS EN 10088-2.
Couplings with a different material makeup are available on request.
Applications
When used individually or combined with bushes, Flexseal Standard Couplings have many applications in the construction, repair and maintenance of pipe systems:

Bushes can be used to accommodate differences between pipe OD’s which fall outside the limitations of the coupling
Flexseal Drain Couplings, sometimes referred to as couplers, are simple, easy to use drainage pipe connectors. Drain Couplings are designed to connect two pipes with the same or similar (within 10mm) outside diameter.
