The Waterway 400-3090 self-aligning union is designed for compatible in-line chlorinator applications using 1-1/2 inch slip connections on both sides. A self-aligning union is especially useful in feeder systems because it helps simplify service and reconnection while allowing the assembly to come together more cleanly.

Unions are valuable anywhere equipment may need to be removed or serviced, and the self-aligning design can make installation more forgiving when exact positioning is difficult. This makes it a smart replacement when the original union is worn, leaking, or no longer aligning as it should.

For in-line chlorinator service and plumbing refresh work, this Waterway union provides a dependable way to restore a more service-friendly connection.

  • Waterway self-aligning union
  • 1-1/2 inch slip x 1-1/2 inch slip connection
  • Designed for compatible in-line chlorinator systems
  • Helps improve serviceability and reconnection
  • Supports a cleaner and more dependable plumbing fit
