Zodiac – Air purge end cap – R0598400

The Zodiac Air Purge End Cap (R0598400) is a genuine OEM replacement component designed for use with Zodiac pool filtration and cleaning equipment. This small but essential fitting serves as the terminal cap on the air purge assembly, sealing the purge point and allowing controlled release of trapped air from the hydraulic circuit. Proper air purging is critical to maintaining efficient water flow and preventing loss of prime in pool filtration systems. Without a correctly functioning end cap, air can re-enter the system, reducing hydraulic performance and potentially causing pump cavitation or reduced cleaning effectiveness.

Technical characteristics and construction

As a genuine Zodiac spare part, the R0598400 is manufactured to the exact tolerances and material specifications of the original component it replaces. The end cap is constructed from durable, chemically resistant polymer suitable for continuous immersion in chlorinated and treated pool water. Its compact design allows for straightforward installation without specialist tools. The fitting is engineered to provide a secure, leak-free seal on the air purge port, ensuring the integrity of the hydraulic circuit during normal operation. Based on available catalogue references, this component is associated with Zodiac’s BOREAL filter range and related pool filtration products, making it a direct fit replacement for systems that use this purge assembly configuration.

Suitability and buying context

The Zodiac R0598400 Air Purge End Cap is intended for pool owners and service technicians maintaining Zodiac filtration systems, particularly those within the BOREAL filter series. It is best suited to residential swimming pools where a Zodiac filter unit is installed and the original air purge cap has become damaged, cracked, or lost. Replacing a worn or missing end cap restores correct air management to the system, protecting the pump and ensuring consistent filtration performance. This is a genuine Zodiac spare part, ensuring compatibility and reliability compared to generic alternatives. If you are unsure whether this part fits your specific model, cross-reference the part number R0598400 with your equipment’s documentation or exploded view diagram before ordering.
