Astral 40mm (1 1/2") Threaded Barrel Union for CA & ECA Media Filter Multiport Valves
🏷️ Brand
Astral Pool
📝 Description
The Astral 10651 is a genuine 40mm (1 1/2") threaded barrel union that screws into the threaded ports of the 40mm multiport valve on Astral CA 280, ECA 550 and ECA 650 media filters.
It is the threaded barrel union shown as item 12 on Astral's CA & ECA media filter spare parts diagram. Barrel unions let you disconnect the filter valve from your pool pipework for service or replacement without cutting pipe. Fluidra also lists this union as a spare part for the Filtrite MF media filter and the ZTP Series thermoplastic filters.

💡 Before You Buy
-
Check your valve size. CA 280, ECA 550 and ECA 650 filters have 40mm valve ports and take this union. CA 300, CA 340 and CA 400 filters have 50mm ports, so you need the Astral 50mm Threaded Barrel Union (10652) instead.
-
Valve union, not a pipework union. This threaded union screws into a media filter multiport valve. It is not the union used on the ZX cartridge filter (10649), and for a plain glue-on union in your pipework see the PVC Pressure Barrel Union 40mm.
-
One union per port. The multiport valve has separate Pump, Return and Waste connections, and each union is sold individually. Order one for every connection you are replacing.
🔧 Our Tips
-
Fit the O-ring first. Astral's manual calls for an O-ring between the multiport valve and each barrel union, so make sure it is seated before you screw the union in.
-
Hand tighten only. Tighten the union by hand. Astral states Teflon tape is not required on these connections.
-
Match the markings. Check each pipe goes to the right port on the valve (Pump, Return and Waste) before you tighten everything up.
❓ Common Questions
-
Do I need thread tape? No. Astral's installation manual says the unions are hand tightened with an O-ring and Teflon tape is not required.
-
Which size does my filter need? CA 280, ECA 550 and ECA 650 use 40mm unions (this one). CA 300, CA 340 and CA 400 use 50mm unions.
-
How many do I need? One for each valve connection you are replacing. A full set for Pump, Return and Waste is three.
-
Is it genuine Astral? Yes, this is the genuine Astral part 10651, supplied by Fluidra Australia.
