Kohler identifies it as compatible with many Kohler urinals and certain one-piece toilet models.

🧠 Simple explanation

It’s basically a replacement sealing ring that keeps a Kohler urinal or toilet from leaking where it connects to the drain or flush assembly.

⚠️ Important note

• This is a fixture-specific service part, not a generic wax ring
• Must match the correct Kohler model/application
• Older Kohler toilets often reference GP53410 in service parts diagrams for 2" flapper systems.
