The Hayward SPX4000DLT Strainer Lid (WL7‑553) is an OEM replacement designed specifically for Hayward NorthStar pumps built before 2008. This heavy‑duty, clear lid allows easy visibility into the strainer basket while ensuring a tight, reliable seal that prevents suction leaks and maintains proper pump priming.

Cracked, cloudy, or warped lids can cause air intrusion, reduced water flow, and pump performance issues. Replacing the lid restores optimal circulation and protects the pump from running dry. Built from durable, chemical‑resistant materials, this lid is engineered for long service life in demanding pool environments.
