Hayward SPX0072D Glass Cylinder

What This Part Is Used For
The SPX0072D glass cylinder is used on compatible Hayward flow indicator or sight glass assemblies. It allows visual inspection of water movement within the system.

Why This Part Matters
A cracked or clouded cylinder makes it difficult to confirm proper circulation. That can delay diagnosing flow issues or air intrusion. Replacing the glass restores clear visual monitoring.
