Astral 40mm Barrel Union for ZX Series Cartridge Filters
🏷️ Brand
Astral Pool
📝 Description
The Astral 10649 is a genuine 40mm barrel union for the inlet and outlet connections on the Astral / Hurlcon ZX Series cartridge filter.
It is listed on Fluidra's spare parts diagram for the ZX Series cartridge filter. The ZX range is discontinued, but the filters are still common in backyards, so this union lets you replace a cracked or leaking connection without replacing the whole filter. A barrel union also lets you take the filter off your pipework for service without cutting pipe.

💡 Before You Buy
-
Cartridge filter union, not a media filter valve union. This union suits the ZX cartridge filter. The threaded unions that screw into a CA or ECA media filter multiport valve are different parts: the Astral 40mm Threaded Barrel Union (10651) and the Astral 50mm Threaded Barrel Union (10652).
-
Check your filter. The model name is on the filter body label. This part is for the ZX Series.
-
One union per connection. Each union is sold on its own, so order one for every connection you are replacing.
