Chicago Faucets 892-ABRCF

The Chicago Faucets 892-ABRCF is a commercial-grade 1/2-inch atmospheric vacuum breaker designed as a genuine direct OEM backflow prevention solution for commercial plumbing systems. This essential safety device provides a reliable mechanical barrier against the hazards of back-siphonage, preventing non-potable liquids, contaminated fluids, or chemicals from being pulled back into clean municipal water distribution loops. In rigorous, high-utility environments such as corporate janitorial closets, university research laboratories, stadium washrooms, and commercial kitchen rinsing centers, sharp drops in main line pressure can generate dangerous vacuum siphons. By being installed on the discharge side of the control valve, this atmospheric safety unit automatically opens its internal air vent to break the siphon lock the instant pressure drops, ensuring strict cross-connection control and health code compliance.

Constructed from premium cast brass using Chicago Faucets' signature ECAST construction, this atmospheric unit is formulated with equal to or less than 0.25% lead content by weighted average. This certified low-lead profile ensures full structural safety and strict national regulatory compliance for potable water delivery systems across institutional facilities. It features a robust industrial rough chrome finish (RCF) that delivers exceptional resistance to oxidation, surface scaling, and aggressive cleaning regimens typical of commercial utility areas. Precision-engineered with standard 1/2-inch NPT female thread connections for both the inlet and outlet, it integrates flawlessly with matching rigid or swing gooseneck spouts and service sink configurations. Standardizing on this authentic factory-original hardware guarantees exact physical alignment, streamlines regular maintenance workflows, and ensures long-term operational peace of mind.
