Key parts of the spout include:
- Spout body
- Aerator
- Spray head (for pull-down or pull-out models)

2. Handle Assembly
The handle controls water flow and temperature. Kohler handles come in various styles—single-handle or dual-handle—and are designed to provide ergonomic control.
Main parts include:
- Handle lever or knob
- Handle cap or escutcheon
- Handle cartridge or valve stem
- Set screw (to secure handle to cartridge)

This is the core component that regulates water flow and temperature. Kohler uses different types of cartridges depending on the faucet model, including ceramic disc cartridges, compression cartridges, or ball valves.
Common parts:
- Cartridge or valve stem
- O-rings or seals
- Retaining clip or snap ring
- Spring (for certain models)

4. Aerator
The aerator is a small screen attached to the spout's tip, which mixes air with water to reduce splashing and control flow rate. It is removable for cleaning or replacement.
Key parts:
- Aerator screen
- Aerator housing
- Flow restrictor (sometimes integrated)

5. Mounting Hardware
This hardware secures the faucet to the sink or countertop and ensures a tight seal. It includes:
- Mounting nut
- Mounting washer
- Gasket or seal
- Escutcheon (cover plate)

6. Seals, Washers, and O-Rings
These small but vital parts prevent leaks by creating watertight seals between different components.

Detailed Breakdown of Common Kohler Kitchen Faucet Parts
1. Cartridges in Kohler Faucets
The cartridge is often the most replaced part in a Kohler kitchen faucet because it controls the water flow and temperature. Kohler uses various cartridges:
- Ceramic Disc Cartridges: Known for durability and smooth operation. They contain ceramic discs that slide past each other to control water flow.
- Compression Cartridges: Use washers and a screw mechanism; more common in older models.
- Ball Valves: Found in single-handle models, using a ball with slots and holes to regulate water.
Common issues: Dripping, difficulty turning, or no water flow often point to cartridge wear or damage.
Replacement tips: Always match the cartridge model number with the faucet for compatibility.

2. Aerators and Flow Restrictors
Over time, aerators can become clogged with mineral deposits, leading to reduced water flow or uneven spray. Removing and cleaning or replacing aerators restores optimal performance.
Cleaning process: Unscrew the aerator, soak in vinegar to dissolve mineral buildup, rinse, and reattach.
Flow restrictor: Some aerators include a flow restrictor to limit water usage, which can be replaced if flow rate decreases.

3. Handles and Handle Components
The handle assembly is subject to wear, especially the cartridge stem or the handle itself.
Common parts:
- Handle lever or knob
- Handle screw or set screw
- Handle cartridge or stem
- Handle cover or escutcheon
Signs of failure: Handle feels loose, hard to turn, or leaks around the handle.

4. Mounting Hardware and Escutcheons
These parts secure the faucet to the sink and provide a finished look.
Common parts:
- Mounting nut (usually hex-shaped)
- Gasket or gasket assembly
- Escutcheon plate, especially in multi-hole setups
Installation tips: Ensure all hardware is tightened securely but not over-tightened to prevent damage.
