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.

Kohler Spline Adapter Removal/ Replacement

This spline adapter brought our 15-year old Kohler Revival kitchen faucet back to life! I loosened the old spline adapter in the valve handle by soaking it for 2-4 hours in a 50/50 mixture of water and rubbing alcohol with three drops of dish detergent. I then removed it with a “hooking tool” made from bending the end of a large paper clip into a ¼” hook (see photo). I placed the new spline adapter on the valve stem and then set the valve handle within a ½- degree of perfect alignment.

Back story on part. Kohlet’s tech support told me this part would make my faucet work with my handle. It didn’t. A different cartridge did work with my faucet. Can’t rate their part but I have a firm opinion of their tech support.

Kohler Spline Adapter Removal/ Replacement.

I have a 15-year old Kohler Revival kitchen faucet, 2 valves with ¼ -turn (90-degree-turn) handles. A worn plastic spline adapter allowed the cold-water handle to rotate 360-degrees. After removing the handle, I found that the plastic spline adapter was stuck inside the handle, probably due to a build-up of mineral deposits or other debris over the years. I removed the spline adapter by first letting it soak for 2-4 hours in water with three drops of dish detergent or soaking in a 50/50 mixture of water and rubbing alcohol (isopropyl alcohol) with three drops of dish detergent. Once this liquid penetrates behind the plastic spline adapter, I then removed it with a “hooking tool” made from bending the end of a large paper clip into a ¼” hook. After replacing the spline adapter, the faucet works like it is brand new. The attached photo shows this removal method. What is the purpose of the spline adapter? A Kohler valve cartridge stem has 20 splines, and the handle has 19 splines. By using the plastic spline adapter between the valve stem and the handle, the handle can be adjusted to within less than ½- degree of perfect alignment.

Some of the descriptions said it was ceramic but this is hard plastic. But that will be fine for our shower valve trim. I had bought the wrong valve and realized after shower install was almost complete

Spline Adapters for Dripfree Taps

[This review was collected as part of a promotion.] What can I say? The spline adapters were easy to install. The original spline adapters lasted 10 years so I hope the replacement will do so as well. If not, I know there is a helpful and knowledgeable saleslady just a phone call away who helped me through the process.

Exact fit

[This review was collected as part of a promotion.] These little plastic pieces are easy to lose. I bought them when I replaced a faucet handle assembly.
