A properly sealed chlorinator is essential for maintaining consistent sanitizer delivery and preventing leaks at the equipment pad. When a chlorinator gasket becomes flattened, brittle, or cracked, even a small failure can allow water and chlorine to escape, leading to loss of pressure, chemical imbalance, and corrosion around fittings. The Aladdin Style Chlorinator O-47 Replacement Gasket (O-47-0) is designed to restore a tight, reliable seal in compatible pool chlorinator systems.

This gasket installs at the chlorinator body or cap interface, where it maintains a watertight seal while allowing the unit to be opened for routine tablet refills or service. Over time, exposure to chlorine, heat, and repeated compression causes original gaskets to lose elasticity. Replacing the gasket ensures the chlorinator operates safely and efficiently without leaks.

This is a pool-industry replacement gasket intended specifically for chlorinator applications—not a general-purpose plumbing O-ring.

Why a Chlorinator Gasket Is Critical

Chlorinators operate under constant pressure and chemical exposure. A compromised gasket can allow chlorinated water to leak externally or air to enter the system, disrupting flow and sanitizer delivery. Left unaddressed, this can damage surrounding equipment or cause inconsistent chlorine levels in the pool.

The Aladdin O-47 chlorinator gasket restores the sealing surface between chlorinator components, helping maintain proper pressure, prevent leaks, and ensure predictable chlorine feed.

Designed for Chlorinator Applications

This O-47 style gasket is manufactured to match common chlorinator sealing dimensions and compression requirements. Proper sizing is critical, as a gasket that is too thin or too thick may not seal correctly or may deform prematurely.

Using the correct gasket helps protect the chlorinator housing and allows the unit to be opened and closed without over-tightening.

Built for Chlorinated Pool Environments

The gasket is made from pool-grade rubber formulated to resist chlorine exposure and maintain flexibility under repeated compression. This durability helps the gasket hold its shape and sealing performance over time, even with frequent chlorinator servicing.

For service professionals, it provides a dependable replacement during routine maintenance. For pool owners, it prevents small leaks from becoming bigger equipment problems.

When to Replace the O-47 Chlorinator Gasket

This replacement gasket should be used when:

• Water is leaking from the chlorinator lid or body

• The existing gasket appears flattened, cracked, or brittle

• Servicing or refilling the chlorinator

• Rebuilding or resealing a chlorinator assembly

• Preventing air intrusion or pressure loss

Replacing the gasket is a simple, low-cost step that protects the entire chlorination system.

Practical Maintenance Part for Pool Owners and Service Professionals

For pool owners, replacing the chlorinator gasket helps keep chemical delivery consistent and the equipment pad dry. For service professionals, it is a common wear item that should be replaced during chlorinator service to ensure a proper seal.

A properly sealing gasket helps extend the life of the chlorinator and surrounding equipment.
