Korky 435BP Flush Valve Seal Kit 3 In toilet accessory

Korky 435BP Flush Valve Seal Kit

This kit contains two rubber flush valve seals designed for 3-inch toilet flush valves. It fits Kohler Class Five and Class Six models along with American Standard Champion 3 toilets. The seals are coloured red and constructed from chlorine-resistant rubber. They are intended for homeowners or plumbers repairing a leaking flush valve on compatible toilet models.

Simple installation with two seal options

Installation involves removing the old seal and pressing the correct replacement into the flush valve opening. The kit supplies one seal for American Standard Champion 3 and another for Kohler Class Five and Six, so selecting the wrong seal for the specific toilet model is the most common error. No tools are typically required beyond shutting off the water supply and draining the tank.

Durable rubber resists chlorine degradation

The rubber material is formulated to resist chlorine commonly found in municipal water supplies, which helps the seal maintain flexibility and a tight seal over extended periods. Under sustained exposure to chlorinated water the seal continues to prevent tank-to-bowl leaks without hardening or cracking quickly. The manufacturer backs the kit with a five-year warranty.
