AutoPilot Strainer Screen 2in Union Debris Screen, ST-220 / DIG-220 / Nano | STK0224

Keep debris out and chlorine flowing. The AutoPilot Strainer Screen (STK0224) is the replacement screen that sits inside the 2-inch union manifold of AutoPilot Pool Pilot salt systems, catching leaves, bugs, and grit before they can reach the salt cell. A clean screen keeps water flow correct so your generator reads accurately and makes chlorine as it should. Once the old one clogs, cracks, or wears down, dropping in a fresh screen is the quickest way to restore full flow and protect the cell. This is the current part; it replaces the older number 19064.

Why It Matters

• Guards Your Salt Cell: Traps debris before it can reach and damage the cell, extending its life.
• Keeps Chlorine Flowing: A clean screen means proper water flow, so the system reads and generates correctly.
• Exact-Fit Replacement: Made for the AutoPilot Pool Pilot 2-inch union manifold assembly base.
• Current Part Number: STK0224 supersedes the older 19064 — same screen, updated part number.
• Quick DIY Swap: No tools or special skills needed; replace it in minutes.
