Standard Couplings
(100-620mm diameter)

Flexseal Standard couplings are designed for sewerage, drainage and low-pressure applications up to 1 bar.

Flexseal provide the most extensive range of Standard couplings available in the marketplace, and have revolutionised traditional pipe repair methods over the years.

Flexseal Standard couplings are specifically designed to connect and repair pipelines of different materials or sizes used in sewerage, drainage and other underground applications.

When excavation work is required to repair a damaged pipe, the Flexseal Standard couplings will reduce the amount of time required to fix the problem and will accommodate minor differences in pipe diameter. Larger diameter differences can be installed using a suitably sized bush.

The combination of a durable design and excellent sealing properties enables the Flexseal Standard coupling to provide a reliable seal on rough pipe surfaces such as concrete, and a high performance seal on smooth surfaces such as PVCu.

Standard couplings can be combined with Flexseal Bushes in order to act as an adaptor between pipelines of widely differing outside diameters. The contractor will require a bush when connecting pipes of different materials or sizes i.e. when outside diameters of the joints exceeds 12mm.

Flexseal can also supply Standard couplings with nitrile sleeves.

Installation of a Standard Coupling with Bush

Benefits:

• Durable design ensuring a high performance and reliable seal
• Stainless steel shear band provides excellent resistance to heavy loads and shear forces
• Reduces excavation work
• Complies with WIS 4-41-01 (all public sewers and sewers for adoption)
• Shear band ensures joint flexibility and pipe alignment
• High performance sealing properties of the couplings eliminates need for grouting in most applications

Applications:

When used individually or combined with bushes, the 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 rocker pipe outside manholes or structures
