Genuine OEM Replacement Cartridge

This genuine OEM Gerber 97-058 cartridge and seat set replaces the washerless control unit in GS-305 shower valves. It fits the original valve body without modification and restores factory function. The white finish matches the standard trim supplied with the series. Plumbers and homeowners use it to fix leaks or temperature drift in existing installations.

Sustained Pressure-Balance Operation

The pressure-balance design holds the outlet temperature within a ±3 °F band while supply pressures fluctuate. The anti-scald function reacts continuously during prolonged use, not only during the first seconds of flow. An adjustable temperature limit stop lets the installer set a maximum handle position that remains effective over the life of the cartridge. Internal seals are rated for repeated daily cycling without degradation.

Compatibility Limited to GS-305 Valves

This cartridge assembly is engineered exclusively for the Gerber GS-305 valve platform and will not interchange with other Gerber series or competitor valves. The stem geometry, port indexing and seat dimensions are unique to the GS-305 body. Installers must verify the valve model before ordering because no cross-reference chart is supplied. Buyers needing parts for a different valve series must source the correct model-specific cartridge.

Questions about this item

Does the washerless cartridge generate noticeable heat or noise when the shower runs continuously?

The pressure-balance design maintains a ±3 °F range without any moving parts that produce audible noise or measurable heat during extended use.

What existing plumbing must already be in place for the 97-058 cartridge to install correctly?

A Gerber GS-305 valve body with standard hot and cold supply connections is required; the cartridge and included seats fit only that specific model.

Will the anti-scald limit stop still function if I keep my original GS-305 trim and handle?

Yes, the adjustable temperature limit stop is built into the cartridge itself, so it operates independently of the external trim or handle.
