Gerber DA507838N Ceramic Disc Cartridge 40mm

Product Description

The GERBER DA507838N is a genuine OEM ceramic disc cartridge designed for single-handle faucets with a 40mm disc platform. Ceramic disc cartridges replace the internal valve mechanism that controls water flow and temperature mixing. The ceramic disc design offers a durable, wear-resistant sealing surface that outperforms older rubber-seat valves in longevity and leak resistance. This cartridge is installed by licensed plumbers during faucet rebuilds or when a handle becomes stiff, drips at rest, or fails to hold a temperature setting. It is a direct OEM part sourced from Gerber.

This cartridge is suited for residential and light-commercial single-handle faucet applications where the original 40mm ceramic disc cartridge has worn or failed. Typical install scenarios include bathroom lavatory faucets and kitchen faucets using the Gerber single-handle platform. When the faucet drips, leaks at the base of the handle, or the handle movement becomes gritty or inconsistent, cartridge replacement is the standard corrective repair.

Key Features

• Genuine OEM Gerber replacement cartridge - ensures correct fit and valve geometry
• 40mm ceramic disc platform for precise flow and temperature control
• Ceramic disc construction resists wear and mineral buildup better than rubber-seat designs
• Designed for single-handle faucet configurations
• Direct drop-in replacement eliminates the need for seat grinding or valve rework

Compatibility

Designed as an OEM-style replacement cartridge for Gerber single-handle faucets utilizing a 40mm ceramic disc valve assembly. Verify the disc diameter and handle configuration before ordering.

Installation Notes

Installation is performed by a licensed plumber or qualified service technician. Shut off the water supply at the angle stops or main shutoff before disassembling the faucet. Remove the handle, retaining clip or nut, and existing cartridge before seating the replacement. Consult the faucet manufacturer documentation for correct cartridge orientation, as reversed installation can cause reversed hot and cold flow.
