Internal Coupling DN150 - All 150mm ID Pipes

Icon Internal Couplings

Fernco, previously known as Flexseal, manufactures a wide range of couplings that connect rainwater and wastewater pipelines using the internal surface, we call these ‘Icon’ (internal connection) couplings.

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

Connecting DN100/DN150 with pushfit couplings

Our range of Icon Pushfit couplings are available in various sizes depending on the pipe(s) to be connected.

The connection process couldn’t be easier. Simply clean the internal surface of the pipes to be connected, push the coupling into the problem pipe and push the connecting pipe over the opposite end of the coupling. Designed to provide a reliable friction fit, these couplings are strong and long-lasting.

The Icon Pushfit range consists of six variations designed to provide straight connections to DN100 and DN150 pipes, or to provide adaptor connections when DN100 pipes are connecting to DN150 pipe sizes. Connections can be made to any pipe material via their internal surface.

Can be installed in 30 seconds or less
Quick and easy alternative to a standard 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
Removes internal joint step that is created by connecting two different pipe materials with conventional couplings
Creates a smooth transition between pipe invert levels
Improved jetting resistance
Withstands internal pressure of up to 2.5bar
Conforms to all testing requirements of WIS 4-41-01 and BS EN 295-4:2013

Time Saving

Have you ever come across a pipe that is encased in concrete or another hard material and had to slowly ‘chip away’ the material around the pipe in order to fit a coupling on the external surface? If so, you’ll know that it’s costly, tedious and can take hours.

Or, have you suffered the pain staking effort it takes to achieve a watertight seal on a spirally reinforced pipe? Flexseal’s Icon (internal connection) couplings solve a multitude of pipe connection problems that traditional couplings simply cannot.

We manufacture two types of Icon Couplings, each designed to reduce the time required to make a secure connection:

Icon Pushfit: make a connection in just 30 seconds

Icon Mechanical: reduce connection time from 4-8hrs down to just approximately 1hr

Highways England Approved

In 2017, Fernco, previously known as Flexseal, supported a Motorway project run by Highways England. Icon Mechanical couplings where used to significantly reduce the time taken to connect many of the pipes encased in concrete on that section of motorway. Fernco’s contribution saved Highways England £240k in unplanned work due to problem pipes, resulting in a recommendation by Highways England for the Icon’s to be used as best practice in those scenarios.
