A: Hi Sean, this is Sarah with Kohler Customer Service. I am glad to address your question. This spline adapter will not fit the GP330004 valvet. It is designed for use with the GP77005-RP and GP77006-RP. Thank you for choosing Kohler.
A: Hi, this is Laura with Kohler Co. I am happy to assist you with your question. This part is used on top of the valve in many wide-spread sink faucets. It allows the handle to grip the valve to open the valve. Thank you for choosing KOHLER.
A: This part adapts the spline on the faucet handle to the mating spline on the faucet valve. Why would they make the parts so that they need an adapter? Either there is a subtle reason that I don't understand or someone made the plastic pieces to resolve a design mismatch in these components. I haven't seen this design on other faucets. I'm betting on the second possibility and they ought to give these away free to buyers of this very expensive faucets.
A: This is to protect the spline just in case someone pushes/spins handle to hard. The spline is brass and is weak metal this protects that metal. This way is someone does the above your replace the 2 dollar part instead of the whole valve assembly. This is used all over the world where splines are used.
