Flex-Seal, part of the Fernco group of companies, designs, manufactures and markets high performance flexible couplings for sewerage, drainage, plumbing and vent systems.
Flex-Seal Standard Couplings are specifically designed to connect and repair pipelines of different materials or sizes used in sewerage, drainage and other underground applications.
Large Diameter Standard Couplings
Large Diameter Standard Couplings can be provided to suit any outside pipe diameter and utilising Flex-Seal's advanced production capabilities, any size of coupling can be supplied direct to the site using the Next Day Delivery Service.
These are designed for repairing damaged sewerage, drainage and low pressure pipelines without the need to replace a section.
Extra Wide Couplings
Standard Extra Wide Couplings are designed for use in the repair of cracked pipelines or those subject to local damage. When excavation work is required to repair a damaged pipe, Flex-Seal Extra Wide Couplings will reduce the amount of time needed and the differences in pipe diameter can be accommodated.
Large Extra Wide Couplings provide a watertight method of connecting large diameter concrete pipes. The 300mm width allows greater tolerance in the cutting of the ends of the pipe as well as providing for the movement of the pipe ends due to settlement.
Flex-Seal Drain Couplings are used to connect, repair and maintain drainage systems and other small diameter non-pressure pipelines.
Drain Couplings are designed for use in drainage systems where the resistance to earth loads (usually provided by a Standard Coupling) is not required.
Adaptor Couplings are designed for connecting drainage pipes of differing materials and outside diameters
Adaptor Couplings can also be used to connect all traditional and new pipe systems including structural walled plastic pipes.
Flex-Seal Chemical Couplings provide a flexible and watertight connection on underground drainage systems that require a high resistance to a range of chemical substances.
Flex-Seal Euro Couplings are manufactured to meet the required European Standards for connecting and repairing pipes used in sewerage, drainage and other non-pressure applications up to 0.5bar.
Bushes are designed for use with couplings when connecting pipes of significantly different outside diameters
Flex-Seal can provide two types of Bushes: Fabricated or Moulded
Designed to be used with Flex-Seal 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, Flex-Seal'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.
Flex-Seal Bushes can also be used when a reduction or increase in the pipe size is required by the user. Utilising Flex-Seal'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.
Moulded Bushes are available in a range of sizes for similar applications to fabricated Bushes 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.
Flexible Saddle Connectors
Flex-Seal Flexible Saddles provide a cost effective, quick and easy to use solution for the efficient connection of lateral pipes to concrete or clay pipes.
Flex-Seal Puddle Flanges provide an effective solution against water penetration along the pipe and can be used with many common materials including PE and other plastic pipes, providing that the surface of the pipe is clean, smooth and pore free.
Puddle Flanges ensure a watertight seal where pipes pass through the walls of tanks, swimming pools etc. They can also be used where they pass through the walls of basements, manholes or other structures below groundwater level.
Flex-Seal can provide a range of pipe couplings for small diameter plumbing applications. They are designed and manufactured from high performance EPDM providing an outstanding quality of product.
Flex-Seal Wall Seals provide a secure and leak proof solution to water penetration along the pipe. Moulded Wall Seals are manufactured from 40 IRHD SBR and Fabricated Wall Seals are produced from EPDM.
Flex-Seal End Stoppers are for site air and water testing and also for temporary sealing of new pipework on construction sites.
End Stoppers are manufactured from a polypropylene material with an EPDM seal and can be supplied with or without an air test nipple depending on the application.
Universal Gully Seals
Manufactured from elastomeric material and designed to fit into sockets of all monolithic concrete road gullies, Flex-Seal Universal Gully Seals provide a connection with a range of 150mm nominal bore pipes.
The Gully Seal is available in two sizes and fits monolithic concrete road gullies with a nominal 200mm or 210mm socket.
