Hayward ECX1003 Diaphragm Gasket

Part Number: ECX1003

Description

A diaphragm gasket designed for use in Hayward Perflex D.E. filters (models EC40, EC50A and similar). This gasket helps seal the tube sheet to the filter tank body, preventing D.E. bypass and ensuring proper system performance.

Compatibility & Fitment

  • Fits Hayward Perflex EC40 and EC50A extended-cycle D.E. filter models.
  • Ideal when the filter is leaking D.E. powder into the pump basket or back into the pool, or if you notice that the gasket is flattened, torn or missing.
  • Direct replacement for systems originally equipped with the ECX1003 gasket part number.

Features & Specifications

  • Rubber or elastomeric material engineered for pool water compatibility and chemical resistance.
  • Designed to fit the opening for the tube sheet of compatible D.E. filter models and maintain a secure seal under pressure.
  • Dimensions approximate: 14″ × 14″ × 4″ (as listed for fitment reference).

Installation Notes

Shut off the pump and relieve system pressure before servicing. Open the filter tank and remove the lid or head. Extract the old gasket and clean the sealing surfaces thoroughly. Install the new ECX1003 gasket ensuring it seats evenly in the groove. Reassemble the filter, restore water circulation, and monitor system pressure to confirm proper sealing and performance.

Maintenance Tip

Inspect this gasket each season—if you observe hardening, cracking, flattening or slip of D.E. powder past the tube sheet, replace the gasket to maintain filtration efficiency and avoid equipment strain or premature wear.
