Effortless Chlorinator Maintenance

The AR-PRO Chlorinator Wrench Opener is designed to simplify routine service on Hayward chlorinator lids. This compact tool pairs with two chlorine-resistant O-rings, offering a practical kit that helps you open, reseal, and reset without hassle. The result is a smoother maintenance process and less downtime between tests.

What’s in the kit

  • 1 AR-PRO Chlorinator Wrench Opener—engineered to fit Hayward lids with clean, even torque.
  • 2 chlorine-resistant O-rings—precisely sized for a snug seal and long life.

Key compatibility and fit

  • Designed for Hayward CL200, CL220, and CL2002S chlorinators; inner diameter around 4.82 inches and diagonal 5.81 inches for reliable engagement.
  • O-rings sized to 5.2 inches inner diameter, 5.5 inches outer diameter, thickness 0.2 inch for a secure seal.
  • Also suitable for other chlorinator brands using similar lid configurations, offering broad practicality.

Material and durability

  • Wrench crafted from 50% more durable plastic—resistant to pool chemicals and everyday wear while keeping costs accessible.
  • O-rings made of chlorine-resistant rubber designed for longer service life under regular pool maintenance.

Real-life use cases

When O-rings show wear or a compromised seal, replace quickly to maintain steady circulation. Use the wrench to open lids with controlled torque, reducing the risk of misthreading or damage during routine upkeep.
