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

The Dial 1/4 in. W Yellow Brass Compression Union is your go-to solution for quick, reliable plumbing connections without soldering. Crafted from durable yellow brass, this compression union delivers solid performance in everyday water lines, helping you tackle repairs and new installations with confidence. Its retail-ready clamshell packaging makes it easy to stock, display, and grab-and-go for both DIY enthusiasts and professional installers.

Why this compression union stands out

  • Durable yellow brass construction offers excellent resistance to corrosion and long-term reliability in visible and concealed plumbing runs.
  • 1/4 in end connection sized for standard 1/4 in tubing, providing a straightforward, secure join for compact plumbing layouts.
  • No-solder installation—simply tighten with a wrench to create a leak-free seal, saving time on quick repairs and tight spaces.
  • Compact, retrofit-friendly design fits into confined cabinet spaces and behind appliances where room is at a premium.
  • Retail-ready packaging (clamshell) ideal for display shelves and bundled projects, helping customers identify and purchase with ease.

Ideal applications

Perfect for connecting 1/4 in lines in under-sink updates, appliance hookups, and small-diameter plumbing runs. Whether you’re replacing a worn connector or extending a line for a new appliance, this Dial compression union provides a dependable, readily-available solution.

How to install

  1. Shut off the water supply and relieve any built-up pressure in the line.
  2. Clean and trim the tubing ends to ensure a square, debris-free surface.
  3. Slide the compression nut (and ferrule, if required by your setup) onto the tubing ends and align the union ends with the pipes to be joined.
  4. Tighten each end with a wrench until the connection seats firmly. Avoid overtightening to prevent damage or leaks.
  5. Turn the water back on and check for leaks. If a small drip appears, tighten slightly until the joint is dry.

What you gain with Dial

With the Dial compression union, you gain peace of mind from a proven brass connection built to endure typical household pressure and temperature variations. It’s a practical, time-saving alternative to soldering, ideal for quick fixes, repairs, or any project where a compact, reliable 1/4 in connection is needed. Trust in a brand known for consistent, dependable plumbing fittings that professionals and DIYers rely on daily.

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.
