This is a genuine Zodiac replacement set containing two half-union connectors along with their corresponding gaskets, designed for use with 40\/49 mm pipe connections. The half-union connector system is a standard plumbing fitting used in pool heating and filtration circuits to create secure, leak-free pipe joints that can be disassembled for maintenance without cutting the pipework. This set ensures a reliable and tight connection at key points in your pool system, such as at the inlet or outlet of a heat pump condenser or heating unit.<\/p>\n
Each connector in the set includes its sealing gasket, meaning you have everything required to complete both sides of a union joint. The gaskets provide a watertight seal under normal pool plumbing pressures and temperatures, reducing the risk of leaks at connection points. As a genuine Zodiac factory part, the components are manufactured to the exact tolerances specified for Zodiac pool heating equipment, ensuring correct fit and long-term reliability.<\/p>\n
This set is referenced in the Zodiac 2020 spare parts catalogue under part number A0357800A and is listed in the W20RDU product family. The connectors are sized for 40\/49 mm pipe, which is a commonly used pipe diameter in pool heating and circulation systems. The half-union design allows the pipe connection to be tightened and loosened repeatedly without damaging the pipework, making it particularly practical during servicing or seasonal maintenance. The included gaskets are pre-matched to the connector geometry, eliminating the need to source separate sealing components.<\/p>\n
Because this is an OEM Zodiac component sourced directly from the manufacturer’s spare parts programme, it is manufactured from materials suitable for continuous contact with pool water and the thermal cycling associated with heating equipment.<\/p>\n
This part is intended for pool owners and pool technicians who need to replace worn, cracked, or leaking half-union connectors on Zodiac pool heating equipment. It is particularly relevant for installations using Zodiac heat pumps or heating units where the condenser inlet or outlet connections require maintenance. The 40\/49 mm sizing makes it suitable for medium to large residential pool plumbing circuits. If your Zodiac heating unit is showing signs of leakage at a union joint, replacing the complete connector and gasket set is the recommended approach to restore a reliable seal. Always verify compatibility with your specific Zodiac model before ordering.<\/p>","protected":false},"excerpt":{"rendered":"
