Chicago Faucets 1920-007JKNF
The Chicago Faucets 1920-007JKNF is a genuine OEM replacement seal gasket specifically designed for use with the 1920 Series Thermostatic and Pressure Balancing (T/P) shower valves. This specialized gasket—often identified by its grey color and polyethylene (PE) construction—is a critical component in the sealing of the valve assembly, particularly in units featuring the Auto-Drain™ system. It ensures a watertight connection between internal components, preventing leaks within the valve body and maintaining the integrity of the pressure-balancing mechanism.
Specifications:
- Gray polyethylene
- For use with Auto-Drain™ shower valve trim
Expert Insight:
The 1920-007JKNF is a small but vital part of the 1920 series "quick drain" architecture. If you are experiencing a slow drip from the valve face or if your Auto-Drain™ feature isn't engaging correctly, this seal may be pinched or degraded. Installation Tip: During a cartridge replacement for the 1920-XJKNF, check this gasket for any signs of compression set or tearing. Pro Tip: When reassembling the valve trim, ensure this gasket is seated perfectly flush. Because the 1920 series is designed to eliminate stagnant water after use, a compromised seal here can lead to water remaining in the hose or internal ports, defeating the purpose of the hygienic Auto-Drain™ system.
