The DuraVent 2PPS-BV4 is a set of two B-Vent adapters designed to convert any B-Vent pipe into a chase for PolyPro flex. It is suitable for use when an older appliance has been replaced with a new condensing 90+ appliance. This setup includes an adapter for capping and flex/B-Vent support. The DuraVent 2PPS-BV4 is intended for venting a single appliance, not for common venting.
Ideal for retrofitting B-Vent pipes in high-efficiency heating applications.
