Shear Band Couplings

Introduction to Shear Banded Couplings

Fernco manufactures the most extensive range of shear banded couplings available in the marketplace and has revolutionised traditional pipe repair methods over the years. Fernco 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.

Fernco Shear Banded Couplings have the ability to connect two pipes with the same or similar outside diameter (OD), and also have the flexibility to accommodate small differences in pipe OD’s. When the pipe OD’s are outside of the limitations of a Shear Banded Coupling, ‘Bushes’ can be used to make up the annual space between the smaller pipe OD and the Shear Banded Coupling. 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.

Straight Connections vs Adaptor Connections

Straight Connection - Connect pipes with the same outside diameters simply, with the use of a Fernco Shear Banded Coupling. Adaptor Connection - Connect pipes with differing outside diameters with a Fernco Shear Banded Coupling in conjunction with a Bush(es).

Standard Couplings: 50mm – 620mm

Fernco Standard Couplings are a range of set size shear banded couplings covering the most common connection requirements. With the most comprehensive range and stock holding in the market, Fernco supply the smallest domestic projects to the largest global projects with ease.

Sizes start from 50mm up to 620mm, after which Fernco can manufacture to specific size requirements. See technical datasheet download for list of sizes available.
All Fernco 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.

Applications
When used individually or combined with bushes, Fernco Standard Couplings have many applications in the construction, repair and maintenance of pipe systems:
As a joint for plain ended pipes
Repair and maintenance of existing pipelines
Connecting short and cut lengths of pipe
Making post construction connections to an existing pipeline
Reconnection of laterals on renovated sewers
Introducing a rocker pipe outside manholes or structures
When used with bushes can accommodate differing pipe diameters

Benefits
Withstands an internal pressure of up to 2.5 bar
A proven, tested and durable coupling design ensuring a high performance and a reliable connection
Stainless steel shear band provides excellent resistance to heavy loads and shear forces to ensures joint integrity and pipe alignment
Complies with WIS 4-41-01 (all public sewers and sewers for adoption)
Complies with BS EN 295 Part 4 & EN681-1: 1996 requirements for vitrified clay pipes and fittings
