Leak- and root-proof reducing pipe coupling with high resistance to chemicals, UV, mould and gases – joins different pipe types and sizes.

Reducing pipe coupling for joining pipes of different sizes and materials in gravity systems, such as stormwater and wastewater pipelines. The coupling is made from the patented elastomer compound Fern-Flex™, whose flexibility makes installation easier and provides a secure seal against both infiltration and exfiltration. It suits, for example, plastic, PE, copper, steel, cast iron/ductile iron, concrete, asbestos cement, GRP and vitrified clay pipe, and is also available in versions with a bushing and an eccentric position for larger size jumps. Maximum working temperature is 50°C.
