A Y Mcdonald Aym-72010 1/2x8 Frostproof Sillcock 1/2 in

Product Description

The A Y McDonald aym-72010 1/2x8 is a frostproof sillcock designed for residential and light commercial plumbing applications where an exterior hose bibb must be protected against freeze damage. The valve body is constructed of brass and operated by a handwheel actuator. Inlet connections are 1/2 inch MNPT or compression (C), and the outlet is standard garden hose thread. The frostproof design positions the seat washer inside the heated envelope of the building, draining the exposed stem when the valve is closed to prevent ice formation in cold climates.

This sillcock is used where an exterior water supply point is required, typically installed through a masonry or wood-frame wall. The 8-inch stem length accommodates standard wall thicknesses. Plumbers install it in new construction and replacement service on residential homes and light commercial buildings in freeze-prone regions. It is suitable for connecting garden hoses, irrigation supply lines, and general outdoor water service.

Key Features

• Frostproof design drains stem automatically when valve is closed, reducing freeze risk
• Brass body construction for corrosion resistance in exterior plumbing service
• 1/2 inch MNPT or compression inlet provides flexible connection options
• Garden hose thread outlet accepts standard hose fittings and accessories
• Handwheel actuator for positive manual control without tools
• 8-inch stem length suits typical residential wall penetrations

Compatibility

Designed as an OEM-style replacement or new-installation frostproof sillcock for residential and light commercial exterior plumbing systems with 1/2 inch supply lines.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and depressurize the line before beginning work. The sillcock must be pitched slightly downward toward the outlet so the stem drains fully when closed. Install a vacuum breaker or confirm local code requirements regarding backflow prevention at hose bibb connections.
