Eccentric reducer for domestic sewerage

Home→ Catalog→ Sewerage→ Domestic sewerage→ Pipeline systems→ Fittings for domestic sewerage→ Eccentric reducer for domestic sewerage

Sewer reducers are designed for the installation of pipes of different diameters or from different materials.

Transition elements for mounting pipes with different diameters usually have an eccentric shape.

Sewer eccentric reducers for connecting pipes made of various materials are produced not only for connecting plastic and cast iron pipes (or plastic and steel, plastic and ceramic), but also for switching to pipe threads.
