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

Sigma Electric ProConnex 1/2 in. D Die-Cast Zinc Screw-In Coupling for FMC is purpose-built to deliver dependable, code-compliant connections in Flexible Metal Conduit (FMC) systems. Crafted from durable die-cast zinc, this 1/2 inch diameter screw-in coupling provides a secure, long-lasting junction for dry-location installations, giving electricians and skilled DIYers a reliable option that withstands the rigors of everyday use.

Why this ProConnex coupling stands out

  • Robust durability: Die-cast zinc construction delivers reliable strength and corrosion resistance, helping the connection maintain integrity over time in indoor dry environments.
  • Precise, secure fit: 1/2 in. diameter and screw-in design ensure a tight, vibration-resistant joint that stays put under load and movement typical of electrical runs.
  • Code-grade safety: UL Listed, CSA Listed, and ETL Listed, so you can install with confidence knowing the component meets major safety standards for FMC installations.
  • Targeted for FMC: Specifically engineered for Flexible Metal Conduit, delivering a dependable interface between conduit and fittings in dry-location applications.
  • Simple packaging: Bagged packaging includes one screw-in coupling, making it easy to stock and install as part of on-site projects.

Ideal applications and use cases

  • Residential basements, attics, and garages where FMC is used to protect wiring in dry indoor spaces.
  • Commercial lighting runs in offices, retail, and light industrial settings that rely on durable FMC connections.
  • Repair or retrofit projects where a trustworthy, easy-to-install coupling can quickly restore a secure conduit connection.
  • New installations that follow ProConnex line standards, ensuring a consistent fit across the system.

Practical benefits and how it helps you

  • Predictable performance: The die-cast zinc body resists deformation and maintains thread integrity, reducing the risk of misalignment during tightening.
  • Efficient installation: The screw-in design minimizes installation steps, enabling faster, more precise connections—especially in tight workspaces.
  • Safety and compliance: With UL, CSA, and ETL listings, you’re aligning with recognized safety programs that support code compliance during inspections.
  • Long-term reliability: Built to endure the stresses of indoor dry locations, this coupling helps protect connections from pull-out and loosening over time.

Installation tips and best practices

  • Inspect FMC threads and the coupling’s threads before installation to ensure clean engagement.
  • Thread in by hand to start, then snug with a suitable tool until the connection is secure—avoid over-tightening to prevent thread damage.
  • Use as part of a complete ProConnex FMC installation plan to maintain consistent fit and performance across all components.
  • Store and handle the bagged coupling to protect the finish from abrasion prior to 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.
