The LARSEN SUPPLY CO., INC. S-203-3 is a replacement lavatory faucet stem designed to fit Delta Delex twin-handle faucets. This stem services both hot and cold supply sides and is sold individually per card. It fits into the faucet body to control water flow and temperature on standard lavatory installations. Plumbers and service technicians reach for this part when a worn or damaged stem causes dripping, stiff handle operation, or failure to shut off completely. At 0.24 pounds, it is a compact, direct-replacement component suited for residential bathroom faucet service calls.
This stem is intended for use in twin-handle lavatory faucets, specifically the Delta Delex line referenced by OEM part number 0263. It covers both hot and cold positions, so a single part number addresses either side of the faucet. Typical install scenarios include repairing a dripping lavatory faucet in a residential bathroom where the seat or stem has worn past serviceable condition. One stem is included per card, and the package quantity is six cards per pack for trade restocking.
Compatible with Delta Delex twin-handle lavatory faucets referencing OEM part number 0263, for both hot and cold stem positions.
Installation is typically performed by a licensed plumber or experienced service technician. Shut off the water supply to the faucet at the fixture stop valves or the main supply before beginning stem removal. Relieve line pressure by opening the faucet handles before disassembly. Follow applicable plumbing codes, such as the IPC, and inspect the faucet seat for wear before installing the new stem to ensure a proper seal.
