WHK 4in Frost-Free Hot/Cold Outdoor Faucet — 1/2in MIP to 3/4in GHT, Lead-Free Brass Chrome Finish

This heavy-duty outdoor spigot is made from lead-free brass with a chrome finish and a 4" frost-free stem. It combines a 1/2" MIP inlet for plumbing connections and a 3/4" male garden-hose thread outlet, plus an integrated vacuum breaker to reduce freeze-related damage. The valve accepts domestic hot water up to 140°F in normal operation and withstands higher short-term temperatures, making it suitable for patios, exterior walls, and utility areas where you need year-round access to water.

How does this faucet prevent freezing in winter?

The 4" frost-free design places the shutoff valve inside the warm interior wall cavity, so water drains from the external spout when closed. An included vacuum breaker (pressure relief valve) also helps avoid trapped water that can expand and stress fittings during cold snaps. Together these features reduce the risk of burst pipes and costly repairs.

• 4" extended stem positions shutoff inside heated wall space
• vacuum breaker vents trapped pressure and prevents freeze damage
• brass construction resists cracking from thermal stress

What connection sizes and mounting options does it use?

The unit uses a 1/2" male iron pipe (MIP) thread at the inlet to connect to standard 1/2" NPT female plumbing or fittings. The outlet features a 3/4" male GHT thread to accept most American garden hoses directly. It's designed for horizontal installation through an exterior wall and ships as a single-piece faucet for straightforward replacement or new installs.

• 1/2" MIP inlet for standard plumbing connections
• 3/4" male garden-hose thread (GHT) outlet for hoses
• horizontal wall mounting; supplied as 1 unit for easy install

Is the faucet robust enough for outdoor conditions?

Yes — the spigot is machined from solid lead-free brass and finished in chrome for corrosion resistance and long life. The full-turn metal handle provides reliable control and resists wear from frequent use. Rated for common residential pressure and temperature ranges, it performs well for seasonal exterior usage.

• lead-free brass body reduces corrosion and metal fatigue
• chrome finish improves weather resistance and appearance
• full-turn metal handle for durable operation and positive shutoff

What are the operating limits and safety notes?

The spigot is rated for working pressures up to 125 psi and normal operating temperatures from 32°F to 140°F (0°C–60°C). It can tolerate short-term higher temperatures but should not be used above the maximum rated limits for prolonged periods. Proper installation with an insulated interior supply and adherence to local plumbing codes will maximize freeze protection and durability.

• working pressure: up to 125 psi
• normal operating temperature: 32°F–140°F (0°C–60°C)
• avoid sustained exposure above rated maximum temperatures

Who is this for? Homeowners, contractors, and property managers who need a reliable exterior faucet that supplies both hot and cold water and minimizes freeze risk will find this WHK frost-free hose bibb practical. It suits replacement projects on exterior walls, new builds requiring a durable outdoor spigot, and situations where garden hoses or exterior cleaning tools need a standard 3/4" connection with secure indoor shutoff.
