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 X 1/2 in. Sweat Anti-Siphon Brass Freezeless Wall Faucet is built to stand up to the demands of outdoor water delivery, pairing a durable brass body with a satin finish and smart engineering that protects your supply year-round.

Why this faucet stands out

Designed for reliability in changing weather, this freezeless wall faucet features frost-proof construction and a proven anti-siphon system. The result is a dependable outdoor faucet that prevents backflow into your potable water line while delivering uninterrupted service even in freezing temperatures. The satin finish not only looks clean and modern but also resists corrosion from sun, rain, and irrigation chemicals.

Ideal use cases and practical applications

Whether you’re maintaining a lush garden, prepping garden beds, or supplying a seasonal hose connection, this faucet delivers reliable outdoor water delivery without the drama of freezing pipes. It’s especially well-suited for climates with cold winters where frost protection is essential, and for installers who need a ready-to-wire (MPT to sweat) solution without additional adapters.

Installation and compatibility tips

The end configuration—1/2 in MPT inlet and 1/2 in sweat outlet—provides flexible setup options. Pair it with copper supply lines for a soldered connection or adapt as needed with compatible fittings. Ensure proper mounting against the wall to maximize the 12 inch reach for easy access and hose routing. Regular maintenance—flush before first use and winterize when temperatures will drop—helps maintain optimal flow and longevity.
