Legend Valve 108-105 Frost-free Sillcock 12 Inches T-551

Product Description

The LEGEND VALVE 108-105 is a frost-free sillcock designed for outdoor water supply applications in residential and light commercial construction. Built to the T-551 standard, this sillcock features a 0.5-inch inlet connection and a 12-inch stem length, allowing the valve seat to sit inside a heated wall cavity where it is protected from freezing temperatures. Rated at 125 psi cold working pressure and manufactured under ISO-9002 quality standards, this fitting is a reliable choice for exterior hose bibb installations. Licensed plumbers and general contractors install this type of fitting during new construction and renovation work.

This frost-free sillcock is suited for exterior wall installations in climates where freezing temperatures occur. The extended 12-inch stem keeps the valve seat and washer inside the building envelope, draining residual water from the exposed barrel when the handle is closed. This design reduces the risk of freeze damage to the supply line and the fitting itself. It is commonly installed in wood-framed and masonry exterior walls where adequate wall depth accommodates the stem length.

• Frost-free design with 12-inch stem seats the valve inside the heated wall cavity

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the main water supply and depressurize the line before removing an existing sillcock or making connections. The sillcock must be installed with a slight downward pitch toward the exterior to ensure proper drainage when the valve is closed. Always connect a vacuum breaker or verify the fitting includes backflow protection where required by local code.
