Marlin W2318 Hot Ceramic Cartridge Assembly

Product Description

The MARLIN W2318 is a hot ceramic cartridge assembly designed for use in faucet and valve applications requiring a durable, wear-resistant internal sealing mechanism. Ceramic disc cartridges provide a precise, low-friction seal that controls water flow and temperature. This assembly handles the hot-side function, directing and shutting off the hot water supply within the valve body. Plumbers and service technicians install this type of cartridge during faucet repair or full cartridge replacement jobs where the original ceramic disc or stem assembly has worn, chipped, or begun to leak.

This hot ceramic cartridge assembly is suited for residential and light commercial plumbing applications. It serves as a direct-replacement component in compatible single-handle or two-handle faucet valves where a hot-dedicated ceramic cartridge is required. Installations are common in kitchen, bathroom, and utility sink fixtures. A licensed plumber or experienced service technician handles this replacement as part of routine faucet maintenance or in response to dripping and flow-control failure.

Key Features

• Ceramic disc construction for long-lasting, low-wear sealing performance
• Hot-side designation for correct directional flow and temperature control
• Drop-in cartridge format supports straightforward replacement without full valve body removal
• Durable ceramic material resists corrosion and mineral buildup better than rubber or plastic alternatives

Compatibility

Designed as an OEM-style replacement ceramic cartridge assembly for compatible hot-side faucet and valve applications. Verify valve body model and cartridge dimensions before installation to confirm fit.

Installation Notes

Shut off the hot water supply at the fixture stop valve or main shutoff before beginning cartridge removal. Depressurize the line by opening the faucet to release residual water. A licensed plumber typically performs this service in compliance with applicable IPC and local plumbing codes. Do not force the cartridge into the valve body; confirm orientation markings before seating to avoid damage to the ceramic disc.
