Advance Water Tank Flapper

Advance Water Tank Flapper

This is a replacement 4.25-inch water tank flapper assembly for Terex Advance front discharge concrete mixers. The assembly is a critical component for controlling the water supply on the truck, opening to allow water to flow from the tank for mix consistency and washout. Over time, the original flapper can wear or the spring mechanism can fail, leading to leaks or improper operation. This complete spring-style assembly ensures a proper seal and reliable function, preventing water loss and allowing the operator to manage the water system effectively.

Key Features

• 4.25-inch diameter flapper valve
