Arrowhead Brass 456-04LF Frost Free Hydrant Faucet 4 in

Product Description

The ARROWHEAD BRASS PLUMBING 456-04LF is a 4-inch frost-free hydrant faucet built from red brass and certified lead free. It is designed for outdoor water supply applications where freeze protection is required. The unit features a 1/2-inch male pipe thread inlet on one end and a 1/2-inch female copper pipe inlet on the other, giving installers flexible connection options. Licensed plumbers install this type of hydrant in residential and light commercial settings where a reliable, code-compliant exterior water source is needed year-round.

The 456-04LF is suited for outdoor wall-mounted installations in climates with freezing temperatures. Its frost-free design positions the shutoff valve deep inside the wall, preventing standing water in the barrel and reducing the risk of freeze-related damage. This makes it a common choice for residential exterior faucet replacements, light commercial service connections, and agricultural utility taps where seasonal freeze protection is a code or practical requirement.

Key Features

• Frost-free 4-inch barrel design keeps the shutoff point inside the heated building envelope
• Red brass construction for corrosion resistance in outdoor and buried applications
• Lead-free certified to meet current plumbing code requirements for potable water
• 1/2-inch male pipe thread x 1/2-inch female copper pipe inlet for versatile hookup
• Sold individually for single-unit service replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation hydrant faucet for residential and light commercial plumbing systems requiring a 4-inch frost-free wall hydrant with 1/2-inch connections.

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 water supply and depressurize the line before beginning work. Ensure the hydrant is pitched slightly downward toward the exterior so the barrel drains completely after each use, which is essential for frost-free performance. Do not attach a hose or backflow-creating device to the outlet without a compliant vacuum breaker in place.
