This Flexseal Icon Pushfit Adaptor Coupling is designed to connect two pipes that have a different internal diameter. It removes the internal joint step that is created by connecting two different pipe materials with conventional outside diameter adaptor couplings. This creates a smoother transition between pipe invert levels and aids the natural flow of sewer systems.

Suitable for connecting a DN100 pipe to a DN150, one end of this drainage adaptor can be connected to a pipe with an internal diameter of between 99mm and 103mm, while the other end can be connected to a pipe with a larger internal diameter of between 148mm and 153mm.

Product Features at a Glance:

• Made from ABS & EPDM rubber.
• Can be installed in 30 seconds or less.
• Quick and easy alternative to a standard adaptor coupling.
• Superior joint stability compared to external couplings.
• Pushfit connection – no tools required.
• Can be easily removed and re-used.
• Watertight connection on any pipe material.
• No need to expose external surface of pipe.
• Improved jetting resistance (230bar).
• Withstands internal pressure of up to 2.5bar/36.25psi.
• Temperature range between -50°c to 80°c (constant)/up to 100°c (intermittent).
• Conforms to all testing requirements of WIS 4-41-01 and BS EN 295-4:2013.

Manufacturers Advice: the lip in the rubber is tapered to eliminate steps in the joint and aid natural flow. Bore reduction has been kept to a minimum and is deemed suitable for drainage applications because of these improvements to flow. Ensure that the tapered edge on the rubber sleeve does not fold back when inserting into the pipe. Lubricant may be required, if so use sparingly, water is recommended.

Applications
Traditionally flexible adaptor couplings connect to the outside of pipelines to ensure the internal surface is free from obstruction. However, there are occasions where internal couplings are necessary, such as:

• Pipe has been encased in concrete.
• Pipe surrounded by brick.
• Pipe cut off at the floor or wall, leaving no stub or excess.

Flexseal Icon Pushfit Couplings

Flexseal has been certified by the British Standards Institution (BSI) as a company of assessed capability, with a quality management system which meets the requirements of BS EN ISO 9001:2015. They are the leaders in wastewater connection innovation; utilising the most advanced methods and techniques for precision-manufactured products, all of which comply with or exceed relevant British and European standards to ensure reliability and sustainability.

Their range of Icon (internal connection) couplings are designed to connect rainwater and wastewater pipelines using the internal surface instead of connecting to the outside of the pipes. These internal couplings create a strong permanent connection whilst having minimal impact to natural flow. Tapered edges aid flow and thin coupling wall keeps bore reduction to a minimum.

Features & benefits

• Significantly reduces labour time for connecting problem pipes.
• Watertight connection on any pipe material.
• Connects pipes of differing or irregular outside diameters.
• No need to expose external surface of pipe.
• Pipe stop indicates that the product is properly installed, when it is flush to the pipe end.
• Passes pressure tests.
• Provides shear load protection.
• The whole range conforms to the requirements of BS EN 295-4:2013.
