Hayward TUBE SHEET-TOP/BOTTOM-EC65/75

The Hayward Top and Bottom Tube Sheets for the Perflex EC65 and EC75 series are critical structural plates designed to organize and secure the internal array of flexible filtration fingers. Precision-molded from a high-impact, glass-reinforced thermoplastic, these sheets feature a series of pre-aligned holes that hold the flex tubes in a rigid, vertical configuration, ensuring uniform spacing for optimal water flow and Diatomaceous Earth coating. Their primary mechanical function is to serve as the structural framework for the internal nest assembly, allowing the entire cluster of tubes to move in synchronization during the manual "bumping" process to shed spent filter media. The top sheet provides the connection point for the bump shaft, while the bottom sheet ensures the tubes remain stabilized and properly seated within the tank’s hydraulic path. These components are engineered to withstand significant pressure differentials and the abrasive nature of D.E. powder while resisting chemical degradation from pool sanitizers. For shipping and logistical purposes, the estimated weight of a Hayward Tube Sheet (either top or bottom) for the EC65/75 models is approximately 2.8 pounds in its retail protective packaging, while the actual dry weight of the individual molded plate is roughly 2.2 pounds.
