Larsen Supply Co. Inc. S-814-3 Stem Cartridge

Product Description

The LARSEN SUPPLY CO. INC. S-814-3 is a brass stem cartridge designed as a direct replacement for single-lever tub and shower faucet assemblies. This cartridge controls both hot and cold water flow through a single-lever valve body, making it a common repair part for residential bathtub and shower plumbing. Constructed from brass, it delivers durable performance in high-use wet environments. Plumbers and experienced DIYers rely on this type of cartridge to restore smooth valve operation and stop dripping or difficult-to-turn faucet handles without replacing the entire valve body.

This cartridge is suited for single-lever tub and shower faucet repair applications in residential plumbing. It is sold individually per card and is a practical stock item for service plumbers handling faucet cartridge replacements. The brass construction makes it appropriate for standard residential water supply conditions.
