Where it matters, this increaser shines. Use it when you need a precise, dependable transition between a smaller 3-inch furnace outlet and a larger 5-inch vent run without introducing turbulent airflow or pressure loss. The crimp-on large end simplifies installation by providing a secure, slip-fit connection that resists loosening over time, even in attics or crawl spaces where temperature swings are common.
Practical use cases include:
- Retrofitting an older furnace or water heater vent to accommodate a larger duct path in Type A vent systems.
- Upgrading a 3-inch exhaust line to a 5-inch run to support increased airflow or higher-capacity appliances.
- Reconfiguring existing duct layouts in tight spaces where a clean, metal-to-metal transition is required.
Ideal for homeowners tackling DIY projects with basic HVAC tools and for professionals performing residential installations. The Imperial furnace pipe increaser provides a dependable, ready-to-install solution that minimizes friction losses and maintains a clean, metal-sealed joint—crucial for safe, code-compliant venting in Type A systems.
Tips for best results:
- Verify that the 3 in and 5 in ends align with your existing ducts before assembly.
- Use appropriate clamps or fasteners compatible with 26-gauge galvanized steel to secure the connection.
- Confirm local code requirements for Type A vent components and transitions in your area.
With its galvanized steel construction and boxed packaging, this Imperial increaser is built to withstand the rigors of installation and daily furnace vent operation. It’s a purpose-driven choice for efficient, reliable duct transitions in heating and ventilation projects.
