This Z-Flex 6" back flow preventer is 3" in diameter. This is a must for vertical tankless water heater installations. The damper (back flow) prevents freezing air from coming back down through the vent stack and potentially causing freeze damage to the tankless water heater's heat exchanger, which is not covered under warranty. This single walled, stainless steel, category II/III venting accessory has gasketed connections for a seamless installation.
