The Fluidmaster 5403 is a universal adjustable 3-inch toilet flapper designed for high-efficiency toilets, featuring a durable silicone seal and customizable flush volume settings. It offers a solid frame to prevent twisting and includes an adjustable dial to optimize water usage between 1.28 and 1.6 gallons per flush. It is ideal for quick DIY fixes for ghost flushing, water conservation in homes with hard water or chlorine, and universal replacement in brands like Kohler, Toto, or American Standard.
The American Standard 738920-0070A is a genuine OEM replacement toilet flapper assembly designed specifically for American Standard Cadet 3 model toilets. It offers a reliable, pre-assembled solution for standard 1.6 GPF flushing needs. However, its plastic construction and strict model compatibility limit its versatility and long-term durability compared to premium materials.
