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

Introducing the QuickFitting 1 in. Press in. MNPT in. Copper Adapter — a purpose-built solution for fast, reliable transitions from copper tubing to threaded pipe. Built around a durable copper body, this adapter is designed to simplify potable water and utility installations where a press-to-connect end meets a standard MNPT male thread.

Key benefits that solve real-world plumbing challenges:

  • Solder-free, flame-free installation — attach the 1" press end to copper tubing using a compatible press tool, dramatically reducing install time and eliminating heat-related risks in tight spaces or near combustible materials.
  • Potable-water approved — NSF-listed, so you can trust it for drinking water and other clean-water applications.
  • Underground-rated durability — engineered for buried or outdoor installations, offering reliable performance in challenging environments.
  • Versatile end configuration — one end is a 1" press connection for copper tube, the other is a MNPT (male National Pipe Thread) end for standard threaded fittings, enabling seamless transitions in a single, compact fitting.
  • Corrosion-resistant copper construction — built to endure years of use in both indoor and outdoor settings, resisting corrosion and maintaining a tight seal over time.

Ideal use cases include converting copper lines to threaded pipe runs in residential plumbing, radiant floor heating circuits, outdoor water supply connections, and buried service lines where a robust, leak-tested connection is essential. This adapter is a smart choice for professionals and DIYers who value speed, reliability, and code-compliant materials without sacrificing performance.

How it fits into your project

  • From copper to threaded systems: connect your copper supply line to a threaded component, valve, or fitting with a single, secure adapter.
  • Quick verification: after crimping the press end, perform a standard leak check on the MNPT side to ensure a tight seal before energizing the system.
  • Installation tips: cut copper square and deburr, choose the correct press jaw for your tool, apply an appropriate thread sealant or PTFE tape on the MNPT threads, and tighten per local plumbing codes.

The QuickFitting copper adapter delivers a practical, efficient pathway from press-to-connect copper piping to threaded pipe systems, backed by NSF listing and underground-rated durability. It’s the precise component you reach for when you need a dependable, fast-install solution that meets modern plumbing standards.

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.
