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

Upgrade your plumbing connections with the JMF Company 3/8 in. compression x 1/2 in. sweat brass adapter. This durable brass fitting is designed to bridge a 3/8" compression line to a 1/2" sweat (solder) connection, delivering a secure, code-friendly junction for potable-water systems. With lead-free construction and ANSI certification, it’s built for reliability in real-world installs.

  • Dual-end configuration: 3/8" compression inlet paired with a 1/2" sweat outlet, enabling a seamless transition between compression and sweat piping methods.
  • Brass, lead-free material: Crafted from brass and certified lead-free, offering long-term corrosion resistance and safe use in potable water applications.
  • Wide compatibility: Suitable for aluminum, brass, copper, and plastic pipe materials, making it a versatile choice for renovations and new builds alike.
  • Strong pressure rating: Maximum pressure rating of 400 psi provides confidence in performance for typical residential and light commercial water systems.
  • ANSI certified: Meets recognized standards for compatibility and safety, helping streamline code approvals on job sites.
  • Practical packaging: Sold as a single adapter, ideal for specific repair jobs or stocking a precise fitting when you need it most.

Ideal use cases: Replace a failing 3/8" compression segment with a soldered 1/2" line, retrofit older plumbing to accommodate new fixtures, or connect mixed piping materials without compromising flow or integrity. It’s especially handy in tight spaces where a compact, reliable transition is required.

Installation tips:

  • Shut off water supply and drain the line before starting.
  • For the 3/8" compression side, slide the compression nut and ferrule onto the pipe, snug the nut, and ensure a tight seal when connected.
  • For the 1/2" sweat side, clean the pipe end, apply flux, insert into the sweat fitting, and solder according to standard hot-work practices.
  • Check for leaks after the system is pressurized and re-tighten as needed.

When you’re updating a kitchen, bathroom, laundry, or mechanical room, this JMF Company brass adapter delivers dependable performance without complicating your project. Choose this 3/8 in. compression x 1/2 in. sweat brass adapter for a precise, durable connection that stands up to everyday use.

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.
