An easy, 3-minute DIY repair that saves you from buying a whole new valve assembly.
Why Choose These Replacement Seals?
Perfect Kohler Compatibility
Equivalent to Kohler part numbers K-GP1059291, 2475620, and 1049291. Works on all Kohler toilet tanks with a canister flush valve. (Please note: This is an aftermarket replacement product produced by IMPRESA, not original Kohler).
Creates a Stronger, Quieter Flush
Toilet gaskets wear out over time, causing weak flushes, running water, and loud noises. Replacing this seal restores proper flushing pressure, stops phantom flushes, and results in a quieter, more efficient toilet.
Easy 3-Minute Installation
No need to remove the entire toilet base or disconnect the water supply. Simply follow the included instructions to swap out the old, worn gasket for a new one. It's a simple, straightforward DIY repair.
High-Quality Rubber Blend
Made from a purpose-specific rubber blend that meets or exceeds the quality of OEM rings (based on in-house testing). The IMPRESA 5-pack provides long-lasting durability and top quality at an excellent value.
