Internal Couplings
With our selection of Fernco Internal Couplings, pipes such as plastic, cast iron and steel pipes with the same inner diameter can be joined quickly and easily, regardless of the outer diameter. They are used when, for various reasons, no normal couplings can be used. This is the case, for example, when a pipe is cut flush, a concrete pipe with a foot or a pipe with a damaged or uneven surface.
Product 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

Innovative Rohrverbindungen
Mit unserer Auswahl an Fernco Innenmanschetten lassen sich Rohre, wie z. B. Kunststoff-, Guss- und Stahlrohre mit gleichem Innendurchmesser unabhängig vom Außendurchmesser schnell und einfach verbinden.
Innenmanschetten werden verwendet, wenn aus unterschiedlichsten Gründen keine normale Manschettendichtung zum Einsatz kommen kann. Dies ist der Fall wenn es sich bspw. um ein bündig abgeschnittenes Rohr, ein Betonrohr mit Fuß oder ein Rohr mit beschädigter oder unebener Oberfläche handelt.
Die Produktvorteile auf einen Blick:
- Reduziert die Arbeitszeit für den Anschluss problematischer Rohre erheblich
- Wasserdichte Verbindung an jedem Rohrmaterial
- Verbinden Rohre mit unterschiedlichen oder unregelmäßigen Außendurchmessern
- Keine Notwendigkeit, die Außenfläche des Rohrs freizulegen
- Die integrierte Einschubsicherung ermöglicht eine zuverlässige, sichere und schnelle Montage
- Bietet Schutz vor Scherbelastung
- Gesamtes Sortiment entspricht den Prüfkriterien der DIN EN 295-4
Normalerweise werden Rohre mit Manschettendichtungen über die Rohraußenseite miteinander verbunden. Es gibt jedoch Situationen, bei denen dies nicht möglich ist.

Betonrohr mit Fuß

Rohre mit beschädigter Oberfläche

Bündig abgeschnittene Rohre

Einbetonierte Rohre
Mit unserem Sortiment an Innenmanschetten bieten wir Ihnen dauerhafte und sichere Lösungen für diese Situationen. Somit kann eine Verbindung zweier Rohre über die Rohrinnenfläche ganz einfach hergestellt werden. Zudem sind die Fernco Innenmanschetten so konzipiert, dass der natürliche Fluss des Abwassers etc. durch die Installation im Inneren des Rohres nicht beeinflusst wird.

Internal Coupling ICON
The ICON coupling is a unique internal coupling that seals securely to the inner walls of two pipes and is tensioned from the outside.
Concrete pipes with foot
Pipes with damaged surface
Flush cut pipes
Partially or completely concreted pipes




Product Benefits:
- Apart from the seal, no other materials and no special tools are required
- The ICON complies with the requirements of DIN EN 295-4!
- The connection is permanently tight. No soiling or contamination of the soil by sewage!
- Due to the long service life, there are no additional costs for monitoring and maintenance
- Pressure tight up to 0,5 bar
- For the connection of PVCu pipes of nominal sizes DN 200, DN 250, DN 400 and DN 500, an overrunning sleeve may also be required to meet any diff erences in internal diameter. This is the only way to safely bridge the diameters!
Technical Information:
- Overall width of coupling is 130mm
- Stainless steel components are Grade 1.4301 material. Grade 1.4401 (SS 316) is also available
- 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
- Bushes can be used where there is a significant difference in Diameter
