Chicago Faucets 892-402KDAB

The Chicago Faucets 892-402KDAB is a commercial-grade vacuum breaker assembly kit designed as a genuine direct OEM repair solution for atmospheric backflow preventer units. This comprehensive maintenance kit provides all the essential components necessary to rebuild the critical air-gap mechanics that protect municipal and building water supplies. In high-frequency, demanding environments such as school laboratories, public washrooms, healthcare facilities, and commercial kitchen utility bays, atmospheric vacuum breakers are exposed to continuous water pressure fluctuations, heavy mechanical cycling, and mineral scale buildup. Over time, these punishing conditions cause internal components to stick, crack, or degrade, which compromises the valve's ability to break a siphon and can lead to persistent weeping leaks at the cap. Installing this authentic factory rebuild kit eliminates fluid bypassing and ensures immediate cross-connection control.

Manufactured using Chicago Faucets' signature ECAST construction, this assembly kit features premium-grade materials formulated with equal to or less than 0.25% lead content by weighted average. This strict low-lead compliance guarantees maximum safety and satisfies strict national regulations for potable water systems across institutional environments. The kit comes complete with a chrome cap, O-ring, plastic lock cap, screws, and the core vacuum breaker mechanism, allowing for a thorough overhaul of the valve's interior. Precision-engineered to exact original factory dimensions, these components fit seamlessly into your existing fixtures to prevent the loose tolerances and friction binding common with generic aftermarket parts. Utilizing this genuine factory replacement kit allows facility managers to extend the operational life of their hardware, preserve water conservation goals, and remain fully compliant with regional health and plumbing codes.
