The American Plumbing Partsmaster 98800881 is a single sequential replacement cartridge designed for Kohler faucet assemblies. Sequential cartridges control water flow and temperature through a single-handle mechanism, moving through a set rotation from off to cold, through mixed, and into full hot. This cartridge restores proper valve function when the original component becomes worn, leaking, or difficult to operate. Licensed plumbers and experienced service technicians typically handle cartridge replacements as part of routine faucet repair and maintenance work.
This cartridge is suited for residential faucet repair applications where the original Kohler sequential cartridge has failed or degraded. Sequential valve cartridges are commonly found in single-handle lavatory, kitchen, and tub or shower faucets where the handle rotates through a fixed arc to control both flow and temperature in sequence. Installation is performed during standard faucet service calls without requiring full fixture replacement.
Designed as an OEM-style replacement cartridge for Kohler single-handle faucets utilizing a sequential valve configuration.
Cartridge replacement should be performed by a licensed plumber or qualified technician. Shut off the water supply at the fixture stop valves or at the main before beginning disassembly. Relieve line pressure by opening the faucet handle before removing the cartridge. Follow local plumbing code requirements, including applicable IPC guidelines, when servicing faucet valve assemblies.
