Introduction to Icon ‘Internal’ Couplings

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

Traditionally flexible 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…

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

Fernco Icon Couplings have been specifically designed to 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.

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.

Connecting DN150-DN600 with mechanical couplings

To ensure we provide couplings that exceed water company requirements, we’ve designed a range of Icon Mechanical couplings. These couplings feature a strong stainless steel body that provides excellent resistance to vertical shear loads, protecting pipe alignment over the joint.

These couplings can be inserted into the pipes to be connected and tightened from the outside with a standard 8mm hex head screw bit. When tightened, the stainless steel body expands to compress the rubber sleeves against the internal surface of the pipes creating a watertight seal.

It’s widely known that the external diameters of pipes within the same nominal diameter can differ but so can the internal diameters especially at larger sizes. For this reason, we manufacture Icon Mechanical to specific site requirements to ensure our customers have a coupling that’s exactly as they need it. We manufacture to order within 24hrs and use rapid delivery options to get it on site when it’s needed.

Benefits

Achieves a secure connection where traditional couplings cannot be used
Permanent, watertight and airtight connection is achieved
High quality components
Installation is simple and carried out with everyday tools
Specially designed bushes are available to accommodate small differences in internal diameter, enabling a wide range of pipe combinations to be connected

Features

The Icon coupling features a stainless steel body which compresses the rubber against the internal surfaces of the pipes, when tightened. Other features include:

Available to suit pipes with internal diameters from 150 – 600mm.
Overall width of coupling is 130mm
Stainless steel components are Grade 1.4301 (304) material
Sizes 150mm up to 300mm with single bolt assembly; sizes greater than 300mm with two bolt assembly
Seal has tapered end sections for a smooth transition between the pipe bore and the coupling

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? Fernco’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 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.
