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

Designed by Charlotte Pipe, the 4 in. Hub X 3 in. D Hub ABS Coupling is a dependable hub-to-hub reducer that seamlessly connects a 4-inch ABS main line to a 3-inch ABS branch.

What this reducer is ideal for

When you need to adapt a larger 4" ABS line to a 3" branch, this reducer coupling provides a straightforward, code-conscious solution. It’s suited for dry or wet plumbing scenarios where hub connections are preferred, allowing you to maintain consistent ABS piping throughout the system without compromising flow or integrity.

Installation tips

  • Ensure both pipe ends are clean, square, and free of debris before assembly.
  • Dry-fit the connection to confirm proper alignment, then cement both ends with compatible ABS cement and primer according to manufacturer recommendations.
  • Insert each pipe end fully into its hub, hold steady until the cement cures, and allow the joint to reach full strength before pressurizing the line.

Practical considerations

  • Compatible with standard ABS hub piping systems, offering a reliable transition between 4" and 3" lines
  • Bulk packaging makes it suitable for larger projects, replacements, or ongoing maintenance stock

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.
