Woodford 104-402 Frost-proof Sillcock 8 in 1/2x3/4

Product Description

The WOODFORD 104-402 is an 8-inch frost-proof sillcock designed for outdoor hose bib applications in residential and light commercial plumbing systems. This anti-siphon-style wall hydrant keeps the internal valve seat located inside the heated envelope of the building, allowing water to drain from the barrel after each use and reducing the risk of freeze damage during cold weather. With a 1/2-inch inlet connection and a 3/4-inch outlet, it fits standard supply line sizing used in most residential rough-in configurations. Licensed plumbers and experienced tradespeople install this type of fixture as a code-compliant replacement or new-construction hose bib.

The 104-402 is suited for exterior wall installations where the pipe must pass through a wall to reach a conditioned or semi-conditioned interior space. The 8-inch barrel length accommodates typical residential wall thickness including insulation. It is appropriate for use in climates where freezing temperatures occur seasonally and where a self-draining design is required or preferred by local plumbing code.

Key Features

• Frost-proof barrel design positions valve seat inside the building to prevent freeze damage
• 8-inch barrel length accommodates standard insulated exterior wall assemblies
• 1/2-inch inlet fits common residential copper and CPVC supply lines
• 3/4-inch outlet threads accept standard garden hose fittings
• Self-draining after shutoff reduces standing water in the barrel

Compatibility

Designed as an OEM-style replacement or new-installation frost-proof sillcock for residential and light commercial exterior plumbing applications requiring an 8-inch barrel with 1/2-inch inlet and 3/4-inch outlet connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing code and the International Plumbing Code (IPC) where adopted. Shut off the main water supply and relieve line pressure before removing an existing sillcock or making any connections. Slope the barrel slightly downward toward the outlet to ensure complete self-draining after each use. Do not install without confirming that the valve seat will be located fully within the heated interior space of the building.
