DuraVent PolyPro Flex Male Adapter: changes rigid pipe to flex at the chimney base
The DuraVent PolyPro Flex Male Adapter is the fitting that joins rigid vent pipe to a flexible chimney liner. It sits at the bottom of the chimney, where the rigid PolyPro pipe coming from the appliance meets the flex liner. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. The flex liner does not attach directly to the appliance. At the chimney top, a female adapter joins the liner back to rigid pipe. A flex gasket comes with this male adapter. The 3 to 5 inch flex puller locks onto it to help guide the liner down the chimney.
Choose a 2, 3, 4, or 5 inch adapter to match your flex liner. Before ordering, keep the vent route in mind: plastic vent pipe cannot pass through a fire rated wall or floor. DuraVent also calls for a yearly vent inspection. Need the connection at the chimney top? See the DuraVent PolyPro Flex Female Adapter top fitting. The DuraVent PolyPro Flex Male Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
