Konfix clamp dn50, for SML/KML plain end cast iron pipes 300050

Transition solution for sewage installations

The main task of the Konfix DN50 coupling is to provide a safe and leak-proof connection between socketless cast iron pipes (SML/KML) and plastic pipes, most commonly PVC. These types of components are essential in the modernization of old installations or when connecting different sewage sections where a transition between materials with different mechanical properties is required. Thanks to the special design used in this product, installers can avoid complicated welding or gluing work, while simultaneously achieving a durable connection resistant to vibrations and temperature changes.

Installation flexibility and precision fit

A key advantage of this coupling is its versatility resulting from its precision scaling. The design allows for the placement of plastic pipes with slightly different outer diameters, which is a common problem when working with materials produced by different suppliers. Because of this, there is no need to search for a perfectly fitting component "to the millimeter" – the coupling will adapt to the actual dimension of the PVC pipe, ensuring tightness.

• Fast installation: The connection process does not require specialized tools or long preparation time, which speeds up work on the construction site.
• Material compatibility: It works perfectly as a bridge between traditional cast iron and modern PVC systems.
• Diameter adjustment: The scaling of the coupling allows for the compensation of small deviations in the outer diameter of the plastic pipe.

Application and operating conditions

The product finds wide application in gravity and vacuum installations, both in residential and public utility buildings. This is a solution dedicated to SML (grey cast iron) and KML (enameled grey cast iron) systems, where it is necessary to maintain continuous sewage flow while simultaneously changing the pipeline material.

The coupling supports a nominal diameter of DN 50 mm, making it a standard component for washbasin, bathtub, or floor drain outlets. The connection is made using a socketless, compression method, which eliminates the need for socket seals or additional intermediate connectors. It is worth remembering that the effectiveness of this coupling depends on correctly selecting the PVC pipe diameter within the manufacturer's scaling range and tightening the bolts according to technical recommendations. Such an approach guarantees that the connection will remain leak-proof even under dynamic operational loads typical for sewage systems.
