In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

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 a dependable, purpose-built solution for indoor furnace venting: the Imperial 4 in. x 30 in. Galvanized Steel Furnace Pipe. Crafted for straightforward, lasting performance in residential heating setups, this 4-inch duct delivers a solid combination of durability, ease of installation, and clean, corrosion-resistant venting.

  • Material & construction: 28-gauge galvanized steel provides sturdy, rust-resistant performance in indoor environments. The silver finish helps it blend into typical HVAC layouts while standing up to routine temperature changes in a home setting.
  • Size you can rely on: 4-inch diameter matches standard furnace exhaust piping, with a convenient 30-inch length that reduces the number of joints on many installations.
  • Uninsulated design: This furnace pipe is uninsulated, making it suitable for indoor vent paths where the vent remains within a heated or climate-controlled space. It’s a practical choice for basements, utility rooms, and other interior sections of a home.
  • Packaging you can trust: Boxed for protection during storage and shipping, helping ensure the pipe arrives straight and ready to install.
  • Brand assurance: Imperial is known for reliable HVAC components, offering compatibility with compatible 4-inch venting components and standard fittings.
  • Color & finish: Silver-colored galvanized finish that’s both functional and visually consistent with typical furnace venting systems.

Who this is for
Homeowners tackling indoor furnace venting, HVAC technicians performing replacements or retrofits, and DIYers planning a straightforward 4-inch vent path in living spaces where the vent remains indoors.

Use cases and benefits
- Replacing damaged or corroded indoor furnace pipe in basements, utility rooms, or interior mechanical closets.
- Extending or adapting a 4-inch vent run where insulation isn’t required along the duct path inside heated spaces.
- A quick, reliable component for retrofit projects updating old venting to a galvanized steel pathway with solid, knock-tinish joints.

Installation tips
- Pair with compatible 4-inch duct connectors and clamps for a secure, sealed joint.
- Inspect joints for a snug fit and ensure all connections are straight to minimize airflow resistance.
- Follow local building codes for indoor venting and select any additional fittings (elbows, adapters) accordingly to maintain a safe, efficient exhaust path.

Choose the Imperial 4 in. x 30 in. Galvanized Steel Furnace Pipe for a durable, straightforward indoor venting solution that stands up to daily heating demands while keeping installation clean and uncomplicated.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
