Delta Faucet 57-3366 Vinyl Flapper 2 Inches

Product Description

The DELTA FAUCET 57-3366 is a 2-inch vinyl toilet flapper designed as a direct replacement for standard residential toilets. The flapper seals the flush valve opening at the base of the tank, stopping water flow between flushes and releasing it when the flush handle is actuated. Vinyl construction resists the mineral buildup and chemical degradation that shortens the service life of rubber flappers in treated municipal water systems. This is a straightforward repair part installed by plumbers and experienced DIYers during routine toilet rebuild and leak diagnostics work.

This flapper suits standard 2-inch flush valve seats found in a wide range of residential toilet tanks. It is a common service part on preventive maintenance calls and leak-detection work where a worn or warped flapper is the source of a running toilet. The vinyl material makes it a suitable choice in applications where chlorinated water accelerates rubber deterioration.

Key Features

• Vinyl construction for improved resistance to chlorine and mineral-laden water
• 2-inch seat size fits widely used residential flush valve configurations
• Direct replacement design simplifies installation without special tools
• Durable seal helps eliminate phantom flushing and tank water loss

Compatibility

Designed as an OEM-style replacement flapper for standard 2-inch flush valve seats in residential toilet tanks.

Installation Notes

Shut off the water supply at the angle stop valve below the toilet tank and flush to drain the tank before beginning work. Disconnect the existing flapper from the overflow tube ears and unhook the lift chain from the flush handle arm. Seat the new flapper evenly on the flush valve ring and adjust chain length to allow full flapper lift with minimal slack. A licensed plumber or qualified DIYer can complete this repair; no special tools are required.
