Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Restore a quiet, efficient flush with the Kohler Flush Ball Kit Rubber. This genuine Kohler replacement part is built from durable rubber to deliver a reliable seal and restore optimal performance to your toilet’s flush mechanism.

Why this Kohler Flush Ball Kit Rubber stands out

  • Durable rubber seal designed to create a tight, water-efficient seal that prevents leaks and stops running toilets.
  • Includes hardware and handles for a straightforward replacement—everything you need is in the box for a hassle-free install.
  • Precisely sized with dimensions of approximately 4-3/4" in height, 2" in width, and 2-1/2" in length, engineered to fit Kohler flush ball assemblies commonly found in many Kohler toilets.
  • Genuine Kohler part, backed by the Kohler name for compatibility and reliability in your bathroom repair.
  • Reduce water waste by restoring a complete seal, improving flush performance and preventing unintended water loss.

Perfect for a range of toilet repair scenarios

Ideal for homeowners, maintenance pros, and DIY enthusiasts who want a dependable replacement that keeps their Kohler toilet flushing strong. Use this kit when you notice a running toilet, a weak flush, or a leaky flush valve seal. Replacing the flush ball helps renew flush power without replacing the entire tank, offering a cost-effective, long-lasting solution.

What’s included

  • 1 x Kohler Flush Ball Kit Rubber
  • Handles

Installation and care tips

For best results, install the kit on a standard Kohler flush valve assembly and ensure the seal is seated evenly to avoid leaks. After installation, run a brief test flush to confirm a complete seal and proper operation. Keep spare hardware on hand for future maintenance, and store the kit in a dry place to extend rubber longevity.
