The 5403 Universal 3? Adjustable Flapper adjusts to fit any 3? toilet on the market in just three easy adjustments. The included guide tells you exactly what settings you need for the most popular toilets. And the silicone seal will last up to 10 times longer than a regular flapper. The 5403 Universal 3" Adjustable Toilet Flapper is best for use in 1.6 gallons per flush toilets made since 1994. The 5403 is adjustable for optimum performance, chlorine resistant, and has a solid frame for ultimate reliability. Flappers with a solid frame do not twist and provide the best seal.
