Kohler exact part record
Kohler GP30413: application and identification
GP30413 is a valve cartridge tied to documented Kohler applications. Confirm the model, generation, and installed geometry before purchase.
Direct answer
Kohler identifies GP30413 as a replacement cartridge for specified Valvet two-handle faucet applications. This is a source-backed application, not a fit claim based on visual similarity. Confirm that the faucet uses Kohler's Valvet mechanism; later ceramic valves and visually similar two-handle bodies require different service parts.

Documented application
Kohler identifies GP30413 as a replacement cartridge for specified Valvet two-handle faucet applications.
The relationship should be confirmed in the official service record for the complete faucet or rough-in model. A family name or matching trim is useful evidence, but it is not the same as a model-level parts callout.
Generation and configuration check
Confirm that the faucet uses Kohler's Valvet mechanism; later ceramic valves and visually similar two-handle bodies require different service parts.
Record whether the control is two-handle valvet control and whether the service diagram describes the complete assembly or only the replaceable internal component.
Physical confirmation
Match the removed cartridge's length, stem end, threads, and stop geometry to the official GP30413 image.
Shut off the water and remove the existing part only when the fixture can be safely returned to service. Photograph its installed orientation and keep every retainer for comparison.
Purchase decision
Order GP30413 only when the official model relationship and the installed configuration agree. If either check conflicts, pause and identify the complete faucet or concealed valve before buying.
Do not infer compatibility from color, finish, handle style, or a marketplace photo. Those cues can group candidates, but they do not supersede the manufacturer's parts diagram.
Questions
Before you remove or replace the part
Is GP30413 compatible with every Kohler two-handle faucet?
No. Kohler identifies GP30413 as a replacement cartridge for specified Valvet two-handle faucet applications. Confirm the complete model and generation in Kohler's support material.
Can trim style identify the internal part?
Not reliably. Trim may be shared across valves, retained during updates, or visually similar across generations. Use the rough-in or faucet model and the installed component.
What should I compare after removal?
Compare the stem interface, body dimensions, locating features, seals, ports, rotation or side, and retention method with the official GP30413 service image.
