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

Meet the STZ Industries 3 in. MIP x 3 in. MIP Galvanized Steel Nipple, a rugged, lead-free threaded connector designed to handle demanding plumbing tasks with confidence. At 4 inches long, this nipple delivers reliable reach between fittings while standing up to the rigors of everyday use in water lines, irrigation runs, and heating systems.

  • Dual MIP ends: both ends are 3 in. MIP (male iron pipe) to fit standard female fittings, simplifying installation and reducing the need for adapters.
  • Lead-free construction: engineered for safer potable-water installations where minimizing lead is important.
  • Durable galvanizing: galvanized steel coating provides corrosion resistance in exposed or moisture-prone environments, extending service life.
  • Optimized size and reach: 4-inch length with 3-inch end diameters offers a practical, reliable connector for mid-run extensions and repairs.
  • Performance ratings: rated for up to 200 psi and temperatures up to 400°F, giving you headroom for both residential water systems and hot-water applications.
  • Practical packaging: bagged packaging for clean storage and straightforward ordering.

Why this nipple stands out

Unlike generic connectors, this STZ Industries nipple is purpose-built for dependable, long-lasting performance in real-world plumbing scenarios. The combination of dual 3" MIP ends, galvanized finish, and lead-free composition means you can tackle routine repairs and mid-run connect-and-extend tasks with fewer fittings and less hassle. It’s a practical choice for both professional installers and DIY homeowners who value durability and safety in every connection.

Ideal applications

  • Connecting two female-threaded fittings in water supply lines or irrigation systems
  • Extending runs where space or layout requires a rigid, threaded bridge
  • Replacement installations where a reliable, corrosion-resistant nipple is needed
  • Hot-water and general-purpose piping up to high-temperature expectations

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.
