The Zodiac R0674200 is a genuine replacement air relief threaded cap designed for use with Zodiac Boreal sand filter systems. The air relief screw and its threaded cap form a critical safety and maintenance component on the filter tank lid, allowing the operator to safely release trapped air from the filter housing before opening the tank or after backwashing. Without proper air venting, pressure can build up inside the filter body, making it unsafe to open. This small but essential part ensures that the depressurisation process can be performed correctly every time.<\/p>\n
As a genuine Zodiac spare part, the R0674200 is manufactured to the exact tolerances and materials specified for the Boreal filter range. It threads directly onto the air relief assembly located on the top of the filter lid, providing a secure, watertight seal during normal filtration operation. The threaded design ensures the cap remains firmly in place under system pressure while still allowing quick manual removal when venting is required. The component is produced from durable, chlorine-resistant materials suited to the wet and chemically active environment of a swimming pool plant room.<\/p>\n
The R0674200 air relief threaded cap is specifically designed as a replacement component for the Zodiac Boreal sand filter series. The Boreal range is a widely used family of sand filters available in multiple tank sizes, covering above-ground and in-ground residential swimming pool installations. If your existing air relief cap is cracked, stripped, or no longer seals correctly, replacing it with this genuine Zodiac part restores safe and reliable operation immediately. Installation requires no tools \u2014 the cap simply threads onto the existing air relief fitting by hand, making this a straightforward maintenance replacement that any pool owner can carry out.<\/p>\n
Because this is an OEM component sourced directly from Zodiac, it ensures full compatibility with the Boreal filter’s existing thread profile and sealing surface. Using non-genuine or ill-fitting caps risks cross-threading the fitting or creating a leak point at the top of the filter lid, so specifying the correct genuine part is strongly recommended.<\/p>\n
This part is intended for owners and service technicians maintaining Zodiac Boreal sand filters. It is suitable for residential pool installations where the Boreal filter is in use. If your filter is showing signs of air leaking from the top of the lid during operation, or if the existing cap has become damaged or lost, the R0674200 provides a direct like-for-like replacement. It is a low-cost consumable spare that is worth keeping on hand as part of a standard pool maintenance kit, given its role in safe filter servicing. Always ensure the filter system is fully depressurised and the pump is switched off before removing or replacing the air relief cap.<\/p>","protected":false},"excerpt":{"rendered":"
