The Flex-Seal range is the most comprehensive range of fully approved rubber flexible couplings for low and non pressure applications throughout the world.
Flexible couplings are ideal for connecting or repairing damaged pipe systems that are the same, similar or different pipe materials or sizes.
Applications include sewerage, drainage, plumbing and vent systems that are manufactured from any pipe material including plastic, clay, concrete, cast iron and steel.
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.
Burdens Civil are proud to represent Fernco Australia Pty Ltd, the Australian subsidiary of the worldwide Fernco group of companies. Fernco is the global leader in high performance flexible couplings. Burdens Civil distributes a full range of products for plumbing, sewerage and drainage applications.
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 .
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.
