Chicago Faucets 892-402KJKABNF

The Chicago Faucets 892-402KJKABNF is a commercial-grade vacuum breaker internal assembly and repair kit designed as a genuine direct OEM solution for atmospheric backflow preventer units. Serving as the direct modern evolution of the classic 892-402KDAB model, this comprehensive factory renewal package provides all the necessary components to overhaul and restore the critical air-gap mechanics that isolate building water systems from contamination. In high-demand, high-utility environments—such as school science laboratories, public stadium washrooms, healthcare examination rooms, and commercial restaurant kitchens—atmospheric vacuum breakers are subjected to relentless water pressure spikes, heavy operational cycling, and aggressive mineral scale buildup. Over time, these variables can cause internal poppets and rubber discs to stick, tear, or warp. This results in dangerous back-siphonage risks or continuous, messy weeping leaks from the vent hood. Installing this authentic factory refresh kit corrects fluid bypassing and secures code-compliant cross-connection safety.

Manufactured utilizing 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 all national regulations for potable water delivery across public, institutional, and commercial properties. The comprehensive maintenance kit includes a chrome cap, a high-density sealing O-ring, a plastic lock cap, mounting screws, and the primary internal vacuum breaker mechanism, facilitating a complete, worry-free rebuild of the valve's interior. Precision-engineered to exact original factory dimensions, these components fit seamlessly into your existing fixtures without the loose tolerances, mechanical friction, and premature failures common with generic aftermarket parts. Utilizing this genuine factory replacement solution allows facility managers to optimize maintenance windows, avoid the expense of replacing complete brass valve bodies, and maintain full compliance with health and plumbing engineering standards.
