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

Prier 1/2 in. MPT Anti-Siphon Brass Sillcock delivers reliable, frost-proof performance for outdoor water needs. With a satin nickel finish and a robust brass body, this sillcock is built to withstand the elements while keeping your irrigation and cleaning tasks accessible year-round.

  • Anti-Siphon protection: Integrated backflow prevention helps keep your drinking water supply clean and compliant in environments where outdoor faucets are used.
  • Frost-proof design: Engineered to minimize freeze risk, the valve remains safely inside the wall, allowing you to rely on outdoor water access even in colder months.
  • Durable materials: Brass construction paired with a durable satin nickel finish resists corrosion and wear from frequent use and exposure to weather.
  • Precision shutoff: Half-turn operation provides quick, control-fast shutoff for everyday tasks—from watering beds to rinsing off equipment.
  • Proper sizing for easy installation: 1/2 in. MPT inlet and a 6" overall length make it compatible with standard supply lines and typical exterior mounting configurations.
  • Flow and rating details: Flow Rate: 12; Maximum Pressure: 125; Maximum Temperature: 125 — designed for dependable performance in typical residential settings.
  • Safe and compliant materials: Low Lead Content helps ensure safer drinking-water compatibility wherever this sillcock is installed.
  • Convenient packaging: Sold as a single unit in bulk packaging for easy inventory and streamlined installation projects.

This outdoor freezeless wall hydrant is ideal for homeowners, property managers, and DIY enthusiasts who value a dependable, long-lasting faucet that protects against backflow and freezing. The round handle offers smooth, comfortable operation, while the satin nickel finish maintains a clean, modern look that blends with most exterior hardware and siding.

Practical use scenarios

  • Garden and lawn irrigation hookups where access to water is needed from the exterior of the home or shed.
  • Pressure-washing stations in driveways or patios, providing a quick, controlled water source without worrying about backflow.
  • Seasonal maintenance tasks such as window cleaning, vehicle washing, or filling outdoor containers without lifting heavy piping tools.

Installation and care tips

  • Ensure the supply line matches the 1/2 in. MPT connection for a straightforward install.
  • During winter months, consider local code guidelines for winterization to maximize frost-proof benefits.
  • Periodically operate the handle to prevent sticking and inspect for any signs of leakage around the connections.
  • Wipe the satin nickel finish with a soft, damp cloth to maintain its appearance and prevent mineral buildup.

Choose the Prier 1/2 in. MPT Anti-Siphon Brass Sillcock for a dependable, backflow-protected outdoor faucet that withstands the elements while delivering precise control and a clean finish. It’s a practical, long-term solution for any outdoor water access need.
