Product Overview

Maintain a secure seal in your compatible salt chlorination system with the CMP PowerClean Salt Cell Housing O-Ring. This OEM replacement component seals the connection between the removable salt cell and its housing, helping prevent water leakage during operation. When the existing seal becomes damaged, worn, or missing, replacing it can address the sealing problem while retaining otherwise serviceable equipment. It is a practical maintenance part for pool professionals and homeowners arranging service on a PowerClean salt system.

Ideal For

• Replacing a damaged or missing salt cell housing seal.
• Servicing compatible CMP PowerClean Salt Ultra chlorinators.
• Keeping a replacement seal available for scheduled equipment maintenance.

Key Features

• Original CMP replacement component for specified PowerClean salt systems.
• Fits the designated O-ring channel inside the compatible cell housing.
• Provides the sealing interface around the removable salt cell assembly.
• Available individually for targeted seal replacement.

Benefits

• Helps control water leakage caused by a compromised housing O-ring.
• Allows replacement of the seal without purchasing a complete cell assembly when the remaining components are serviceable.
• Provides a manufacturer-listed part number for accurate replacement selection.

Compatibility

Compatible PowerClean Salt Ultra models include:

• Ultra 320 and 320EXT.
• Ultra 540 and 540EXT.
• Ultra 760 and 760EXT.

Confirm the replacement number against your equipment’s parts diagram before ordering. PowerClean branding also appears on tablet chlorinators, so the product family name alone does not establish compatibility. This listing is for the salt cell housing seal; confirm the location of the seal being replaced.

Installation and Service

A qualified pool service professional is recommended to inspect the O-ring, housing, and cap before replacement. Shut off equipment power and relieve system pressure according to the equipment manuals before opening the assembly.

CMP specifies that this PowerClean Salt Ultra O-ring and its seating channel must remain clean and that no lubricant should be applied. Correct seating and cap alignment are essential to proper sealing.

What’s Included

One CMP PowerClean salt cell housing O-ring. The electrolytic cell, cell housing, cap, and control center are sold separately.

Confirm Before Ordering

Match the manufacturer part number and equipment model. If leakage continues after seal replacement, have the housing, cap threads, and cell assembly inspected to identify the underlying cause.

Specifications

Customer Q&A

Does this include a replacement salt cell?

No. This item includes only the housing O-ring. The cell and related assemblies are separate components.

Should I lubricate this O-ring?

No. CMP’s PowerClean Salt Ultra instructions specifically prohibit lubricant on this seal.

Will replacing this O-ring fix every housing leak?

No. Replacement can address a damaged seal, but improper seating, cap problems, or damaged components require separate attention.

Can I select this part by pool size alone?

No. Match your chlorinator model and manufacturer part number. Pool gallon capacity alone does not identify the correct replacement seal.
