Fernco roll rings

The roll ring belongs to Fernco's range of flexible pipe fittings and is used for internal installation in pipes, where the seal is made from inside the pipeline. The products are designed for gravity systems, such as drainage systems, and for joining pipes of different materials and sizes. The ring is made from the patented elastomer blend Fern-Flex™, whose flexibility makes installation easier and provides a reliable seal against both infiltration and exfiltration on pipes of, amongst others, PVC, PE, copper, steel and cast iron/ductile iron. The material is leak-proof and rot-resistant, with high resistance to chemicals, ultraviolet radiation, mould and gases in drainage systems. Maximum working temperature is 50 °C and maximum pressure is 0.3 bar.
