Internal Pushfit Couplings

Connect From the Inside

ICON Internal Pushfit Couplings create fast, watertight 4" and 6" sewer and DWV connections from inside the pipe.

Fernco ICON Internal Pushfit Coupling features

When the Outside of the Pipe Isn't an Option

ICON connects from inside the pipe, making it especially useful in applications where the outside pipe wall is difficult or impossible to access.

Whether the pipe is surrounded by concrete, brick or other surrounding materials, the internal pushfit design provides a practical way to restore the connection without relying on the exterior pipe surface.

Above or below ground. Vertical or horizontal. ICON is designed for sewer and DWV applications in a wide range of installation conditions.

Built for the Connections Traditional Couplings Can't Reach

ICON approaches the pipe connection differently — from the inside.

Internal Connection

Installs inside the pipe, making it ideal for sheared-off pipe and situations where the exterior pipe wall cannot easily be exposed.

Watertight Seal

Creates a permanent seal against infiltration and exfiltration across compatible sewer and DWV pipe materials.

Maintains Flow

An internal lip and tapered edge create a smooth transition designed to minimize disruption to the flow path.

Fast Pushfit Installation

No installation tools are required. The integrated pipe stop provides a clear indicator when the coupling is properly positioned.

One Coupling. Multiple Installation Positions.

ICON is engineered for both vertical and horizontal sewer and DWV connections.

Horizontal Connections

Use ICON for horizontal sewer and DWV connections where exterior access is limited or an internal pipe connection provides the most practical installation method.

Vertical Connections

The same internal pushfit design can be used in vertical piping, providing installation flexibility across repair and connection conditions.
