WHK Frost-Free Outdoor Faucet Sillcock 12-inch, Lead-Free Brass, 1/2" Push-Fit Inlet, Vacuum Breaker

The WHK 12" Frost Free Outdoor Faucet Sillcock is a lead-free, heavy-duty frost-proof hose bib with an integrated vacuum breaker and push-to-connect inlet designed to prevent freezing, backflow, and leaks.

Built for cold climates and simple DIY replacement, this 12-inch sillcock combines a durable brass body, chrome finish, and a 3/4" female GHT hose outlet with a 1/2" push-fit inlet. It meets UPC, NSF, and CSA standards and is intended to stop pipe bursts in freezing weather, block contaminated water from re-entering potable lines, and speed up installation without soldering or glue.

How does this sillcock keep water lines safe in winter?

The frost-free design positions the valve seat farther inside the heated portion of the wall so water drains from the exposed spout after shutoff, reducing freeze risk. An integrated anti-siphon (vacuum breaker) prevents contaminated outdoor water from flowing back into your home's supply.

• 12" length moves the shutoff point inside warm wall cavities
• Vacuum breaker stops backflow and potential contamination
• Lead-free brass resists corrosion in freezing cycles

What makes installation quicker and tool-free?

The WHK sillcock uses a 1/2" push-fit inlet compatible with PEX, CPVC, PE-RT, and SDR-9 HDPE pipes, allowing fast connections without crimping, glue, or soldering. A mounting flange secures the valve to wood or masonry surfaces for stable, professional-looking installation.

• 1/2" push-fit connects to common pipe materials instantly
• Can be installed on wet lines—no drying or curing required
• Mounting flange included for wall stability and alignment

Is the WHK sillcock durable and leak-resistant?

Made from solid lead-free brass with a chrome finish, the unit resists corrosion and holds up to seasonal stress better than plated zinc or plastic alternatives. The multi-turn metal handle provides tight valve seating for reliable shutoff and reduced leakage.

• Solid lead-free brass body for long-term durability
• Chrome finish adds corrosion resistance and easy cleaning
• Multi-turn metal handle offers precise, leak-free control

Which hose and pipe sizes does this spigot accept?

The outlet is a standard 3/4" female GHT thread to fit garden hoses and accessories, while the inlet is a 1/2" push-fit for interior pipe. Confirm your hose thread and supply pipe type before ordering to ensure a correct match.

• 3/4" female GHT outlet fits most garden hoses and sprinklers
• 1/2" push-fit inlet accepts PEX, CPVC, PE-RT, SDR-9 HDPE
• Ideal for retrofit replacements and new exterior walls

Who is this for? Homeowners, contractors, and property managers who need a reliable frost-proof outdoor faucet will benefit from the WHK 12" sillcock. It’s aimed at anyone replacing a seasonal spigot or installing a new exterior water outlet in cold climates, and for DIYers who prefer a fast, tool-free connection while meeting UPC/NSF/CSA standards. If you want a corrosion-resistant, lead-free solution with anti-siphon protection and a standard garden-hose outlet, this WHK frost-free sillcock is designed to simplify installation and reduce winter plumbing risk.
