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.
