Manthorpe Flexi Pipe Adaptor

The Manthorpe Flexi Pipe Adaptor (GTV-AD) enables you to convert a Manthorpe in-line roof tile vent into a reliable outlet for mechanical extraction systems or soil stack ventilation. Designed to work in conjunction with the GRPA Flexible Pipe range, this adaptor transforms the rectangular vent outlet into a standard 4-inch circular connection, ready for straightforward ducting.

Whether you're venting a bathroom extractor fan or terminating a soil pipe through the roof, the adaptor provides a quick and secure fit by clipping directly onto the vent outlet. It creates a tight seal, allowing you to run ducting easily through the roof space using a compatible flexible pipe extension. A 4" to 3" reduction adaptor is also available for narrower pipe connections.

Perfect for both new build and retrofit applications, this component ensures a professional, watertight connection between roof tile vents and extraction ductwork.
