Frost-Proof Sillcock for Outdoor Use
This Zoro Select anti-siphon sillcock supplies water to exterior walls while resisting freeze damage in cold climates. The 6-inch stem length suits standard wall thicknesses for residential and light-commercial installations. Chrome-plated brass construction provides corrosion resistance for prolonged outdoor exposure. An integrated vacuum breaker prevents backflow contamination of the potable supply.
Verify Inlet Compatibility and Local Codes
Confirm the existing supply connection matches the 1/2-inch solder cup or male NPT inlet before ordering. The handwheel handle requires sufficient clearance to operate fully after installation. Local plumbing codes may mandate additional backflow protection beyond the built-in ASSE 1019 device. California Proposition 65 warnings apply due to listed chemical content.
Pressure Rating and Operating Characteristics
Rated for a maximum working pressure of 125 psi under normal conditions. Chrome-plated brass body and aluminum handwheel handle typical seasonal temperature swings without leaking. Frost-proof function relies on the interior shut-off seat draining automatically when closed. No external power or moving parts beyond the valve stem are involved in daily operation.

Questions about this item
Does the Zoro Select 104-513 sillcock include mounting hardware or solder fittings, or must they be purchased separately?
The product is supplied as the sillcock valve only. Mounting hardware, solder cups or MNPT adapters are not included and must be sourced separately.
Should I choose the solder-cup inlet or the MNPT inlet version for a half-inch copper supply line?
Both inlet types accept a half-inch connection. Select the solder-cup version for direct copper pipe sweating or the MNPT version for threaded pipe or adapter fittings.
What does the 125 psi maximum pressure rating mean for everyday outdoor use?
It indicates the valve body is tested to withstand 125 psi, which exceeds typical residential supply pressure and provides a safety margin for normal outdoor water demands.
