Zodiac eXO housing seal
Diagram position: 11
Shaped seal for the control-unit housing. Compare the complete groove and original seal; this is not the round O-ring used on the electrolytic cell.
Catalogue reference: WR0823600.
Pool specialist’s view
Shaped seal for the control-unit housing. First locate the exact source of a leak. A new seal is useful only when its groove, thread and mating surface are sound; replacing a ring will not repair a cracked housing.

Replacement and checks
Before opening the water circuit, switch off the equipment, stop circulation and release pressure as instructed. Clean mating surfaces and inspect seals. Avoid overloading plastic threads during reassembly and check for leaks after restarting.
If unsure about the version, send photos of the original component and equipment label to info@chemie-bazen.cz.
Position in the assembly
The blue arrow identifies the component in the original drawing. The unmarked original is retained in the gallery.

Choosing this part correctly
Match the original seal by its position in the assembly and part code. A chlorinator may contain several similar-looking rings with different functions. A stretched or compressed used ring may no longer match the size of a new part.
What to check during replacement
Clean the groove and mating surface before assembly. Avoid twisting or pinching the seal. Once circulation resumes, check the joint under normal operating conditions.
