The Hayward SPX4000DLT Strainer Cover Kit is an OEM replacement designed specifically for NorthStar pump models manufactured before 2008. This clear, heavy‑duty lid provides a tight, reliable seal that prevents suction leaks, maintains prime, and protects internal pump components from air intrusion.

Its transparent design allows easy visual inspection of the strainer basket, making routine maintenance faster and more convenient. Ideal for replacing cracked, cloudy, or warped lids that reduce pump efficiency.
