DuraVent PolyPro Flex Female Adapter: connects the chimney liner to rigid pipe at the top
The DuraVent PolyPro Flex Female Adapter is a fitting that joins a flexible chimney liner to rigid PolyPro pipe. It goes near the top of the chimney, where the flexible part of the vent ends and rigid pipe takes over. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. A flex gasket, the seal for the liner connection, comes with the adapter. Choose a 2, 3, 4, or 5 inch size to match your flex liner.
The liner needs a flex gasket at both ends, not just at this upper connection. Each gasket sits in the first complete groove beside the cut end, and the fitting closes around the liner with two locking tabs. Only soapy water should be used on the gasket, never petroleum grease. A qualified professional installs the PolyPro Flex liner, with the vent length limits set by the appliance maker. Need the connection at the bottom?
