Waterco Multicyclone Half Barrel Union - 50mm

Part #6340245 suits Waterco Multicyclone pre-filter units with 50mm plumbing connections. Always verify your specific Multicyclone model number and pipe size before ordering to ensure compatibility.

The kit includes the half barrel union body, lock nut W02647, tail, and O-ring — everything needed for a complete union replacement on your Multicyclone pre-filter.

Half barrel unions can crack, leak, or have their threads strip over time due to UV exposure, water pressure, and regular maintenance cycles. A leaking union will cause water loss and reduced filtration pressure. Replacing it restores a watertight connection between the Multicyclone and your pool pipework.

This is a 100% genuine Waterco OEM spare part. Using genuine parts ensures correct fit, sealing performance, and protects your equipment warranty.
