The 110mm Universal Flexible Underground to Rainwater Adaptor is a versatile transition fitting designed to bridge the connection between above-ground rainwater downpipes of various shapes and sizes and standard below-ground drainage systems. Manufactured from durable, weather-resistant polymer materials, this flexible adaptor is engineered to withstand outdoor exposure, UV radiation, and ground pressure, ensuring a dependable link that accommodates minor misalignments between surface and subterranean pipework.
 
Featuring a flexible, stepped, or multi-diameter collar design, the adaptor can accommodate a wide range of standard downpipe profiles—such as circular or square pipes of different dimensions—and securely couple them into a standard 110mm underground drainage pipe. This flexibility eliminates the need for rigid, custom-molded reducers when dealing with non-standard or older downpipe systems, making it an invaluable problem-solving component for retrofits and complex installations.
 
Designed for quick and straightforward installation, the adaptor provides a tight grip around incoming pipes to prevent leaks, splashing, and moisture ingress around building foundations. Its resilient construction maintains a secure seal while absorbing minor vibrations and thermal expansion. Whether you are modernizing a residential rainwater system or completing a challenging drainage connection, this universal flexible adaptor delivers professional-grade adaptability, watertight security, and long-term convenience.
