How to use
To install the insert, first ensure the water supply is turned off to prevent accidental discharge. Remove the existing handle by loosening the retaining screw or pulling it off, depending on the specific faucet model. Once the handle is removed, extract the old or damaged insert from the handle cavity. Align the new KFA plastic insert with the square profile of the valve stem and press it firmly into the handle until it is fully seated. Reattach the handle to the valve stem and secure it with the original screw to complete the installation.
What to consider before purchase
Verify the compatibility of your current handle model with the square insert design
Check the condition of the valve stem to ensure it is not the source of the mechanical issue
Ensure you have the necessary tools, such as a screwdriver or hex key, for handle removal
Usage recommendations
For optimal performance and to prevent damage to the new component, do not overtighten the handle retaining screw during reassembly. Ensure the insert is properly aligned with the valve stem before applying pressure to avoid cracking the plastic material.
