The KOHLER GP42361 is a replacement index button designed for use in KOHLER faucet and valve trim assemblies. The index button serves as the decorative cap that conceals the handle screw, giving the faucet a finished appearance while protecting the fastener beneath. This small but essential component is a direct OEM replacement part, typically installed by licensed plumbers or experienced service technicians during faucet repair or trim replacement. At 0.214 pounds, it is a lightweight hardware piece that fits precisely into the handle assembly it is designed for.
This index button is suited for residential plumbing applications where KOHLER faucet handles require repair or cosmetic restoration. It is commonly replaced during routine faucet maintenance, handle re-installation, or when the original button has become cracked, discolored, or lost. The part is appropriate for use in bathroom and kitchen faucet trim work where restoring original appearance and protecting the handle screw is required.
Designed as an OEM-style replacement index button for compatible KOHLER faucet handle assemblies. Verify fitment against the original trim series before ordering, as index button profiles vary across KOHLER product lines.
Installation is typically performed by a licensed plumber or qualified service technician. Shut off the water supply to the fixture before beginning any faucet disassembly. The index button is generally press-fit or snapped into the handle cap recess — avoid using sharp tools that could damage the surrounding trim finish. Follow all applicable local plumbing codes during service.
