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 1-1/2 in. Sweat X 1-1/2 in. D Sweat Copper Tee, a three-way copper fitting designed for soldered (sweat) joints on 1-1/2" copper tubing. This lead-free, NSF-listed tee provides a reliable branch connection in residential and commercial copper systems, delivering strong performance under hot and cold-water service and in radiant heating loops. With all three ends sized 1-1/2", it integrates seamlessly into standard copper runs, offering a permanently leak-tight connection when soldered with conventional lead-free flux and solder.

Key benefits

  • Three 1-1/2" sweat ends: creates a sturdy branch tee for copper piping without additional adapters
  • Lead-free copper construction: safe for potable water, reducing potential lead exposure
  • NSF-listed: compliant for use in potable water systems
  • High-duty ratings: maximum working pressure up to 408 psi and maximum temperature up to 400°F, suitable for hot water, cold water, and radiant heating scenarios
  • Permanent, leak-resistant joints: designed for reliable soldered connections with standard flux and lead-free solder
  • Brand trust: manufactured by NIBCO, a long-standing name in copper fittings and plumbing solutions
  • Packaging: 1 piece per package for easy handling and on-site use

Applications and use cases

  • Residential and commercial potable water distribution where a clean branch from a 1-1/2" supply line is needed
  • Hydronic and radiant heating circuits requiring a reliable 3-way copper branch connection
  • Repairs, retrofits, or new installations in copper piping networks that rely on sweat fittings for durability and longevity

Installation at a glance

  • Prepare copper ends: clean, deburr, and dry the tubing for optimal solder joints
  • Apply an even coat of lead-free flux to pipe ends and the inside of the fitting
  • Insert pipes fully into each sweat port and heat evenly with a torch until solder flows smoothly
  • Supply the correct amount of lead-free solder, allow joints to cool naturally, and inspect for uniform, bright joints

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.
