Cold Stem for Kohler Fixtures

This compression stem fits Kohler single-hole faucets and controls cold water flow. It is made from brass for durability and corrosion resistance. The part is supplied new and ready for immediate installation.

Replaces Worn Compression Stems

Swapping this stem restores positive shut-off when the original seat or washer has eroded. The upgrade is worth it when dripping persists after washer replacement or when handle travel becomes inconsistent. It addresses the specific failure mode of compression cartridge wear.

Direct Thread-In Installation

The stem threads into the existing valve body using standard plumbing tools. Common issues include cross-threading during reassembly and forgetting to shut off supply lines before removal. Applying pipe-thread sealant on the threads helps prevent seepage after reinstallation.

Questions about this item

Does the 2-1/2" x 1" brass stem fit my Kohler single-hole faucet?

Yes, the stem is specified to fit Kohler brand faucets and is designed for cold-water use in single-hole configurations.

What tool and orientation are needed to install this compression stem without stripping the brass threads?

Use an adjustable wrench on the hex base, turn clockwise until snug, then back off a quarter turn; over-tightening crushes the compression washer and causes leaks.

How often should I replace the rubber washer inside this cold-water stem?

Inspect the washer annually; replace it at the first sign of hardening or dripping — typically every two to three years in normal residential use.
