Product Overview
The Gerber GA507978 is a replacement washerless cartridge for compatible Gerber valve assemblies that use its pressure-balance and anti-scald functions. The cartridge helps control mixed-water temperature and volume while responding to sudden pressure changes between the hot and cold supplies. If one supply is interrupted, the stored product information identifies an instant shutoff function intended to reduce the risk of an uncontrolled temperature change.
An adjustable temperature-limit stop allows the maximum mixed-water setting to be restricted during installation, while adjustable volume control supports normal operation of the compatible valve. Cartridge fit is model specific. A similar appearance does not confirm compatibility, so the complete faucet or valve model, original cartridge number, stem configuration, and service instructions should be verified before ordering.
