Quick overview
- Three pieces in one kit Cover, lock ring and O-ring together, so the whole sealing face is renewed at once.
- Genuine Hayward Factory part SPX5500D for the Power-Flo Matrix pump.
- Power-Flo Matrix Made for the SP1590 series pump body, not a universal lid.
- Cures a stubborn prime A crazed cover or a flattened O-ring pulls air and is a common reason a Matrix will not hold prime.
- Plastic construction Molded to the original Hayward specification for the Matrix strainer pot.
- Clear view of the basket A fresh cover lets you see basket loading again instead of guessing at it.

Product details
The Hayward SPX5500D is the strainer cover kit for the Power-Flo Matrix SP1590 series pump. It comes as the cover, the lock ring and the O-ring together.
Why the whole kit
These three pieces work as one seal. A new cover on a worn lock ring, or a good ring on a hardened O-ring, still leaves a path for air. Replacing them together restores the seal properly and saves a second order two weeks later.
The symptom
Air at the lid rarely shows as a leak, because the pump is pulling on that side rather than pushing. What you see instead is a pump that will not prime, a basket area that never fills completely, or bubbles arriving at the returns. Crazing or hairline cracks in an old cover and a flattened O-ring are the usual causes.
Fitting note
Wipe the sealing groove clean before the new O-ring goes in, and put a light film of pool rated silicone lubricant on it. It seals better and the cover will still come off by hand next season.
