Matco-norca 212012 Frostproof Sillcock Anti-siphon 1/2 in X 12 in

Product Description

The MATCO-NORCA 212012 is a frostproof sillcock with an integrated anti-siphon valve, designed for outdoor hose bib applications in residential and light commercial plumbing systems. The unit features a 1/2 inch hose outlet and a 1/2 inch MIP/SWT inlet connection, allowing installation into sweat-soldered or male-threaded supply lines. At 12 inches in length, the valve stem extends far enough into the wall to keep the water shutoff point above freezing temperatures, protecting the supply line during winter conditions. Licensed plumbers and pipefitters are the typical installers. This sillcock carries IAPMO, CSA, and ASSE certifications, confirming compliance with major plumbing code standards.

The 212012 is suited for exterior wall installations where freeze protection is required. The 12 inch stem length accommodates standard wall depths and keeps the internal seat and water inside the conditioned or insulated envelope of the structure. The anti-siphon feature prevents backflow from a connected garden hose from contaminating the potable water supply, a requirement under most current plumbing codes. This valve is appropriate for new construction and replacement applications in single-family homes, multi-family buildings, and light commercial structures.

Key Features

• Frostproof design with 12 inch stem keeps water shutoff inside the heated wall cavity
• Integrated anti-siphon valve provides built-in backflow protection for potable water supply
• 1/2 inch MIP and SWT inlet options support both threaded and sweat-soldered connections
• IAPMO, CSA, and ASSE certified for compliance with major plumbing codes and standards
• 1/2 inch hose outlet fits standard garden hose fittings

Compatibility

Designed as an OEM-style replacement or new-installation frostproof sillcock for residential and light commercial exterior plumbing applications requiring a 1/2 inch supply connection and a 12 inch stem length.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and relieve pressure in the line before beginning work. When using the SWT inlet, ensure the pipe and fitting are fully cleaned and fluxed before soldering; keep heat away from valve components to avoid damage to internal seals. The hose bib must be pitched slightly downward toward the outlet so water drains completely from the stem after the valve is closed, maintaining freeze protection.
