InnoFlue Polypropylene Increasers & Reducers

InnoFlue® Increasers and Reducers provide a versatile solution for adapting vent diameters within polypropylene exhaust systems. These components are designed to allow smooth transitions between different pipe sizes while maintaining proper flue gas flow and overall system performance. Common size transitions include the 1 inch to 3/4 reducer, also referred to as a 1 to 3/4 reducer or 1in to 3/4 reducer, as well as larger transitions such as the 4 inch to 3 inch reducer.

As part of the InnoFlue® polypropylene vent system, InnoFlue® increasers and reducers are evaluated to UL 1738 and ULC S636 by ICC and are rated for flue gas temperatures up to 230°F (110°C). Their durable yet lightweight polypropylene construction supports long-term reliability while simplifying handling and installation in a wide range of venting applications.

InnoFlue® reducers, including options like the 1 inch to 3/4 reducer and 4 inch to 3 inch reducer, are engineered to help optimize vent layouts by allowing installers to adapt to appliance requirements and space constraints without sacrificing efficiency. All InnoFlue® increasers and reducers install quickly and easily without the use of glues, primers, or solvents, helping reduce installation time and complexity.
