Chicago Faucets 823-013JKNF

The Chicago Faucets 823-013JKNF is a genuine, commercial-grade OEM replacement internal spring engineered specifically to regulate mechanical return action within specialized self-closing cartridges. Positioned as an upper spring component inside the cartridge stem assembly, this heavy-duty hardware piece provides the calibrated compression force needed to ensure automatic valve shutoff. Over millions of cycles in busy public facilities, original internal springs suffer from inevitable material fatigue, which leads to slow, erratic mechanical shutoffs or faucets that fail to close entirely. Replacing the compromised component with this direct factory part restores the fixture to its original operational standards.

Manufactured from high-strength spring steel, the 823-013JKNF is designed to resist snapping, structural deformation, and the aggressive effects of treated municipal water chemistry. It integrates seamlessly into series 825-X and 826-X self-closing push-button cartridges, ensuring precise mechanical alignment and stable tension cycles. By choosing this authentic factory-spec replacement, commercial facility managers and plumbing professionals can optimize water conservation, minimize localized mechanical friction, and significantly extend the service life of high-use public hand-washing infrastructure.
