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 Anvil 1/8 in. FPT x 1/8 in. FPT Black Malleable Iron Coupling — a compact, dependable connector engineered for small-diameter piping projects. This coupling features female pipe threads on both ends, designed to join two 1/8" FPT components in tight spaces with a solid, reliable connection.

  • Two 1/8 in. FPT ends — provides a precise, consistent connection for 1/8" threaded components.
  • Malleable iron construction with a durable black finish — built to withstand everyday use in common piping tasks while maintaining a tidy, professional appearance.
  • Compact profile — ideal for installations where space is limited, such as crowded valve manifolds, wall cavities, or maintenance on compact lines.
  • Straightforward installation — simple threaded connections that pair with compatible 1/8" FPT fittings and adapters for quick repairs or retrofits.

What this coupling solves

When you need to extend or link small-diameter lines without bulky connectors, this Anvil coupling provides a dependable, easy-to-use solution. Its malleable iron body offers robust mechanical strength for everyday plumbing, shop, or light industrial tasks, while the black finish helps maintain a clean, professional look in exposed or semi-exposed installations.

Ideal uses and scenarios

Use this 1/8" FPT x 1/8" FPT coupling to connect two male-threaded 1/8" components in compact assemblies, such as service lines, small-diameter manifolds, or tight-angle runs where space constraints prevent larger connectors. It’s well-suited for maintenance and retrofit work, DIY projects, and educational demonstrations where precise, small-scale threading matters.

Installation tips

  • Clean threads before assembly to ensure a snug, leak-free fit.
  • Apply an appropriate thread sealant or Teflon tape compatible with metal pipe threads—wrap in the direction of tightening to prevent unraveling.
  • Tighten by hand to seat the end threads, then secure with a wrench just enough to achieve a firm connection without over-tightening.
  • Check for alignment after installation and ensure the connected components are properly supported to minimize stress on the joint.

Why choose this Anvil coupling

Designed for reliability in small-scale piping tasks, this black-malleable-iron coupling blends sturdy construction with a clean finish. It provides a straightforward, space-saving solution for connecting 1/8" FPT components, making it a practical addition to any toolbox, maintenance closet, or workshop inventory.
