Ceramic Cartridge for Single-Handle Faucets FERRO GW1, 40 mm, High

FERRO GW1 is a 40 mm ceramic cartridge for single-handle faucets, designed to replace or repair kitchen and bathroom mixers that use a high-profile cartridge. The unit uses ceramic discs to regulate water flow and temperature, providing a stable seal and reduced dripping compared with conventional rubber-seated valves. The high housing profile helps accommodate faucets with elevated lever positions and supports straightforward installation in compatible fittings.

Advantages

The ceramic discs ensure precise control of flow and temperature with minimal wear, extending service life and reducing the need for frequent maintenance. Its 40 mm diameter fits standard single-handle faucets that accept 40 mm cartridges, and the high-profile design offers easier access for operation in mixers with taller spindles. The construction materials are chosen for corrosion resistance and consistent performance under typical household water conditions.

Suitable for

• Repair or replacement of single-handle kitchen faucets compatible with 40 mm cartridges
• Repair or replacement of single-handle bathroom mixers compatible with 40 mm cartridges
• Installations where a higher cartridge profile is required for lever clearance

When it may not be suitable

This cartridge is intended specifically for single-handle faucets designed for 40 mm ceramic cartridges; it will not fit mixers that require a different cartridge diameter or a two-handle valve system. Additionally, faucets with integrated electronic controls, thermostatic systems, or proprietary cartridge shapes may be incompatible.

Key specifications

• Cartridge diameter: 40 mm
• Type: ceramic disc cartridge for single-handle faucets
• Profile: high (elevated housing for taller levers)
• Function: controls water flow and temperature with ceramic sealing
• Intended environment: domestic kitchen and bathroom mixers

How to use

Turn off the water supply before removing the handle and escutcheon of the faucet. Extract the old 40 mm cartridge according to the faucet manufacturer's procedure and inspect the valve body for debris or mineral buildup. Insert the FERRO GW1 cartridge into the valve body in the correct orientation, secure any retaining clips or nuts, and reassemble the handle and trim. Restore the water supply and cycle the lever to check for smooth operation and leaks; if leaks occur, verify seating and connections.

What to consider before purchase

• Confirm your faucet accepts a 40 mm ceramic cartridge and requires a high-profile unit
• Check the cartridge orientation and retaining mechanism used by your mixer model
• Inspect the valve body for damage or heavy scale that could affect sealing

Usage recommendations

For reliable performance, ensure the water supply is shut off during replacement and test the cartridge under normal operating conditions after installation. If hard water is present, consider cleaning the valve body before fitting the new cartridge to improve sealing and longevity.
