Standard Couplings (100-620mm diameter)

Fernco Pty provide the most extensive range of Standard Couplings available in the marketplace and the Flexseal range has 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, Flexseal Standard Couplings will reduce the amount of time required and minor differences in pipe diameter can be accommodated. Larger diameter differences are 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 e.g. concrete, and a high performance seal on smooth surfaces e.g. PVCu.

Standard Couplings can be combined with Flexseal Bushes in order to act as an adaptor between pipelines of widely differing outside diameters. A Bush will be required by the contractor when connecting pipes of different materials or sizes i.e. when outside diameters of the joints exceeds 12mm.

Fernco can also supply Flexseal Standard Couplings with nitrile sleeves.

  • For sewerage, drainage and low pressure applications up to 2.5 bar.
  • 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

Adaptor Couplings (35-420mm diameter)

Flexseal Adaptor Couplings are manufactured to meet and exceed the stringent requirements of the drainage marketplace.

Adaptor Couplings provide a solution to many cases of adaptation. The coupling is a stepped moulded elastomeric sleeve that has different diameters at each end. The sleeve is fitted with two stainless steel clamping bands which provide an efficient method of connecting pipes that have varying outside diameters and also eradicates possible bush requirements.

Adaptor Couplings can also be used to connect all traditional and new pipe systems including structural walled plastic pipes.

A special range of Adaptor Couplings which incorporate an extra wide clamping band at one end are available for ribbed pipe systems. The clamping band secures against two or more external ribs on the plastic ribbed pipe thereby ensuring a high performance seal is obtained irrespective of the coupling position or movement.

Flexseal can also supply Adaptor Couplings with nitrile sleeves .

  • Provides a quick and efficient method of connecting pipes of differing materials and outside diameters
  • Low cost alternative to using Bushes

Bushes (11-2100mm diameter)

Designed to be used with Flexseal Standard Couplings, Bushes are available in a range of sizes and thicknesses that allow for the adaptation between all pipe materials and types.

Fabricated from an elastomeric strip, Flexseal's Fabricated Bushes are manufactured to suit specific site dimensions and are used when there is a significant difference in the outside diameter (greater than 12mm) of the pipes to be connected or if an Adaptor Coupling is not available.

Flexseal Bushes can also be used when a reduction or increase in the pipe size is required by the user. Utilising Flexseal's advanced production processes and techniques, thicker Bushes can be manufactured with a profiled cross section which enhances the seal on rough pipe surfaces and provides a high performance seal on low pressure pipes due to an increase in the effective sealing pressure.

Flexseal can also supply Fabricated Bushes with nitrile sleeves.

  • Can be manufactured to suit specific site and application requirements
  • Provide a high performance seal on low pressure pipes
  • Versatility in application enables the bush to be used when a reduction or increase in pipe size is needed
  • Manufactured to meet the WIS standard
