Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the Imperial 5 in. D X 3 in. D Galvanized Steel Furnace Pipe Reducer, a purpose-built connector designed to transition from a 5-inch furnace vent to a 3-inch duct with reliability and ease. Crafted from durable galvanized steel and finished in a corrosion-resistant silver, this reducer stands up to the demands of residential and light commercial heating installations.

  • Size that fits your system: Large end 5 in diameter, small end 3 in diameter.
  • Material you can trust: 26-gauge galvanized steel for long-lasting strength and corrosion resistance in damp or humid environments.
  • Connection type: End Type: Crimp on Small End, providing a secure, airtight fit to a 3" duct for reliable performance.
  • Vent compatibility: Type A vent compatibility makes it suitable for common furnace venting configurations.
  • Finish and packaging: Silver color with carton packaging for easy handling and storage.
  • Product application: Specifically designed as a furnace pipe reducer to streamline transitions between round duct sizes in heating systems.

Why this reducer stands out

Unlike generic adapters, the Imperial furnace reducer combines the strength of galvanized steel with a precise 5" to 3" transition, ensuring minimal leakage and stable airflow. The 26-gauge wall provides a balanced blend of rigidity and flexibility, making installation straightforward without sacrificing durability. The crimp-on small end delivers a secure connection to your 3" duct, reducing the risk of loosening over time and helping maintain efficient venting under temperature fluctuations.

Ideal use cases

Perfect for projects where a 5" furnace outlet must couple with a 3" vent line—whether you're replacing worn components in a residential furnace setup, upgrading an aging system, or completing a retrofit where space constraints demand a precise reducer. This reducer is well-suited for basements, utility rooms, and other HVAC environments where dependable duct transitions are critical to performance and safety.

Practical installation guidance

For a secure, airtight connection:

  • Inspect both duct ends to ensure clean, undamaged surfaces before assembly.
  • Slide the 5" duct into the large, 5" end of the reducer and align for a straight run.
  • Attach the 3" duct to the crimp-on small end, ensuring a snug fit without forcing the joint.
  • Use appropriate sealing methods per local code to minimize air leakage and maintain system efficiency.

The Imperial 5 in. D X 3 in. D Galvanized Steel Furnace Pipe Reducer delivers a durable, code-ready solution for efficient furnace venting. When you need a reliable 5" to 3" transition built to endure in challenging environments, this reducer is a practical, proven choice.
