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

Introducing the NIBCO 1-1/4 in. Sweat X 1-1/4 in. Sweat Copper Coupling—a precision copper fitting designed for durable, leak-tight connections on 1-1/4 in copper piping.

  • Lead-free copper construction provides safe, compliant performance for potable water applications.
  • Sweat-to-sweat configuration with both ends as sweat fittings delivers reliable solder joints on copper pipe.
  • Maximum working pressure: 439 psi making it suitable for typical residential water systems and light-commercial setups.
  • Brand reliability from NIBCO, known for consistent tolerances, corrosion resistance, and long-lasting performance.
  • Single-piece design simplifies installation by reducing the number of joints and potential leak points.

Ideal use scenarios:

  • Repairing a damaged section of 1-1/4 in copper supply line by replacing a failed coupling.
  • Extending copper runs in kitchens, bathrooms, laundry rooms, or basements with solid, soldered connections.
  • Replacing corroded joints in both hot and cold potable water lines for long-term reliability.

Installation notes to get the best results:

  • Clean and deburr copper pipe ends, apply flux, and heat evenly to form a clean, watertight solder joint on each end.
  • Ensure proper alignment before soldering to prevent misfits and reduce the need for rework.
  • Inspect joints after cooling for any signs of cold joints or solder bridges.

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.
