Hayward SPX5500K Strainer O-Ring (Power-Flo Matrix)

Hayward SPX5500K is a genuine replacement strainer O-ring used on the Hayward Power-Flo Matrix pump series. This O-ring helps create a watertight seal at the strainer/pump housing connection to reduce leaks and air intrusion that can cause prime loss.

  • Brand: Hayward
  • Type: Strainer O-ring / housing seal
  • Common Compatibility: Hayward Power-Flo Matrix pump series (SP1590 family)
  • Pool Type: In-ground (commonly listed)

Common Compatibility (Verify Your Pump Model)

  • Hayward Power-Flo Matrix pumps: SP1591, SP1592, SP1592FT, SP1593 (commonly listed)

Common Symptoms This O-Ring Can Fix

  • Drips or seepage at the strainer housing connection
  • Air bubbles in the pump basket
  • Prime loss or difficulty priming after cleaning
  • O-ring looks flattened, cracked, sticky, or brittle

Installation Notes

  • Turn off power and relieve pressure before opening the pump.
  • Remove the old O-ring and clean the groove and mating surfaces (remove grit/sand).
  • Install the new O-ring evenly (do not stretch excessively).
  • Use a light coat of pool-safe silicone lubricant to improve sealing and prevent pinching.
  • Reassemble and check for leaks once the pump is running.

Maintenance Tips

  • Clean and lubricate O-rings lightly during seasonal service to reduce drying and cracking.
  • Never use petroleum-based grease on pool O-rings.
  • If leaks persist after replacement, inspect the housing for cracks or warped sealing surfaces.
  • Keep the pump lid and strainer area clean to prevent debris from pinching seals.
