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

Mr. Heater Brass Excess Flow Male Plug delivers dependable safety and reliable sealing for propane systems. Built from solid brass with a gold finish, this excess flow male plug is designed to integrate with Mr. Heater equipment and standard hose fittings, giving you a trusted component for outdoor heating, grilling, and RV setups.

  • Brass construction provides robust corrosion resistance and durable performance in outdoor and field environments.
  • Excess-flow protection helps minimize gas flow if a line is disturbed or disconnected, adding an essential safety margin during storage, transport, or maintenance.
  • Compact, one-piece design ensures a secure seal with a simple, reliable connection to the male port and compatible hoses or fittings.
  • Gold/brass finish offers easy identification in toolkits and on-site, helping you grab the right connector quickly.
  • Packaging comes in clamshell packaging, keeping the plug protected and ready for inclusion in your propane toolkit (one piece per package).
  • Compatibility intended for use with Mr. Heater propane systems and common hose fittings found in residential and recreational setups.

Ideal for: campers, RV owners, backyard enthusiasts, and professionals who rely on propane gear and want an extra layer of safety when hoses are detached or during system maintenance.

Practical use cases include temporary sealing during transport or storage, safe disconnection for hose replacement, and quick restoration of a secure port in field conditions without sacrificing safety.

How to use: Before connecting or disconnecting hoses, ensure the line is depressurized and clean. Thread the plug into the male port until snug—avoiding overtightening—and verify the connection is secure. When reattaching hoses, remove the plug and inspect all fittings for cleanliness and tightness before re-pressurizing the system. Store the plug in its original packaging to protect the port when not in use.

For a compact, durable solution that enhances safety and compatibility in propane setups, the Mr. Heater Brass Excess Flow Male Plug stands out as a practical, purpose-built choice. Add it to your toolkit and experience the security of a well-sealed, reliably protected gas connection.

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.
