Shear Banded Couplings

Flexseal shear banded couplings are specifically designed to connect and repair pipes on adopted sewer and drainage applications, recommended for Water Authority systems. The stainless steel central band protects the joint under vertical shear loads and helps to keep the joining pipes aligned, helping to prevent pipe displacement.

Withstands an internal pressure of up to 2.5 bar
Stainless steel shear band prevents pipe displacement
Less excavation compared to replacing a whole length of pipe
Complies with AS/NZS 4327-1995 – Metal-banded flexible couplings for low-pressure applications
WaterMark certified
OceanaMark certified
WSAA appraised

Introduction to Shear Banded Couplings

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 Water Authority (adopted) sewer and drainage applications.

Shear banded couplings are recommended when connecting onto Water Authority assets as they provide added protection and perform to a higher standard than non shear banded couplings.

The shear band on this range of couplings gives the connection added protection against vertical 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 Shear Banded Coupling.

Adaptor Connection

Connect pipes with differing outside diameters with a Shear Banded Coupling in conjunction with a Bush(es).

Standard Couplings: 50mm – 620mm

Flexseal 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, Flexseal supply the smallest domestic projects to the largest global projects with ease.

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

All Flexseal Standard Couplings are manufactured in accordance to ISO 9001:2015 and comply with AS/NZS 4327-1995 – Metal-banded flexible couplings for low-pressure applications, suitable for Water Authority drainage and sewers.

Applications

When used individually or combined with bushes, Flexseal 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 AS/NZS 4327-1995 – Metal-banded flexible couplings for low-pressure applications
Complies with BS EN 295 Part 4 & EN681-1: 1995 requirements for vitrified clay pipes and fittings

Large Couplings: 300mm – any size

All of Flexseal’s Large Diameter Couplings are made to order for specific projects, meaning each coupling is a perfect fit for the pipe that it’s made for. All that Flexseal needs to know is the outside diameter and material of the pipes to be connected.

Flexseal large couplings feature unique high torque bolts which maximise the contact pressure between the coupling and the pipe, thus providing a strong, reliable seal. Each large Flexseal coupling is supplied with a 13mm socket with 3/8” square drive to ensure installers are well equipped.

Large Coupling Variants

Large couplings are 190mm wide as standard but depending on the application it’s sometimes necessary to opt for a wider option. Flexseal can offer the following widths made-to-measure to any pipe diameter from 300/400mm.

Large Couplings

Size range: 400mm +
Width: 190mm

Application: Used to connect two plain ended pipes above 400mm, usually in cases when drainage lines are being extended and therefore socket connections are not present. Connections to concrete pipes above 400mm should use Large Couplings opposed to Standard Couplings.

Extra Wide Large Couplings

Size range: 400mm +
Width: 300mm

Application: Used to connect two pipes where a cut section has left the pipe end uneven or not square to the axis of the pipe; this coupling will bridge the gap. Extra Wide Large Diameter Couplings are usually used as standard on pipes above 1000mm to compensate for this and for improved angular deflection. Extra Wide Large Couplings are to be used on Twinwall pipes from 600mm as the sealing zone covers more ribs than the narrower Large Coupling.

Magnum Couplings

Size range: 300mm +
Width: 370mm

Application: Used to connect two pipes where a cut section has left a pipe end severely uneven or not square to the axis of the pipe. Additional bolts with the Magnum Coupling provides extra strength.

WaterMark Certified & WSAA Appraised

“The WaterMark Certification Scheme is a mandatory certification scheme for plumbing and drainage products to ensure they are fit for purpose and appropriately authorised for use in plumbing and drainage installations.” – Australian Building Codes Board

Fernco offers a full range of products which are certified under the WaterMark Certification scheme including Standard Couplings.

“The WSAA National Product Appraisals program is a voluntary scheme introduced by the Water Services Association of Australia to provide a single coordinated appraisal of a product’s conformity to the needs of the urban water businesses. It was developed with industry assistance, and draws on the collective knowledge and experience of the urban water businesses and industry specialists.” – Water Services Association of Australia

Fernco offers a full range of Standard Couplings which are formally appraised by WSAA.
