Chicago Faucets 823-010JKNF

The Chicago Faucets 823-010JKNF is a genuine, commercial-grade OEM replacement internal spring designed to regulate mechanical return action and flow cycles within Chicago Faucets push-button metering cartridges. Operating under constant tension at the core of the cartridge stack, this high-performance spring provides the mechanical force required to push the plunger back into its sealed resting position, completing the automatic shutoff cycle. Over time, millions of push-button cycles, water hammer impacts, and mineral accumulation can cause the original spring to suffer from material fatigue, leading to sluggish button returns, stuck valves, or water that runs indefinitely. Replacing the fatigued component with this direct factory part restores the valve to its original crisp actuation and factory-timed cycle.

Constructed from premium, industrial-grade spring steel, the 823-010JKNF is engineered to resist structural deformation, snapping, and the corrosive elements found in treated municipal water supplies. Its exact wire diameter and coil pitch provide the precise resistance needed to maintain predictable volumetric run times, helping facilities reduce water utility waste. Selecting this genuine factory hardware ensures seamless compatibility within the valve sleeve, minimizing maintenance overhead and maximizing the service life of hand-washing fixtures in high-traffic public restrooms.
