Is your Chicago faucet dripping or not turning on/off properly?

This 377XKLHJKABNF cartridge is likely the exact replacement part you need.

It's a commercial-grade, ceramic disc cartridge designed for a 1/4-turn operation (just a quick 90-degree turn from off to on).

It has a long stem, which is needed for faucets with exposed decorative caps.

The main body is brass, and the internal ceramic components are corrosion-resistant for a long service life.

Importantly, it's made with low lead content (0.25% or less by weighted average), meeting safety standards for potable water.

It's a complete, self-contained mechanism - you just remove the old one and pop this in.

This is an OEM-style part, engineered to fit and function like the original.

Before ordering, make sure this part number matches what's on your old cartridge or in your faucet manual.

A straightforward fix that can save you from replacing the whole faucet.
