1/2" x 8" Freezeless Wall Hydrant with Integral Anti-Siphon Protection

Designed for cold-weather performance, the 1/2" x 8" Freezeless Wall Hydrant delivers dependable year-round access to outdoor water while safeguarding the supply line from freeze damage and contamination. Its extended 8" length is ideal for deeper wall penetrations or thicker insulation zones in residential or light commercial buildings.
