About this cord/connector

The Balboa 2-to-1 AX Y-Cable (Part #25257) is a genuine OEM auxiliary cable designed for Balboa spa control systems. This 6-pin male-to-female Y-configuration cable allows you to split one auxiliary connection into two outputs, essential for spas requiring multiple auxiliary device connections from a single control point.

Built to Balboa's exact specifications, this Y-cable ensures reliable signal transmission and proper system communication. At Bubbles Supply, we guarantee an exact fit for your spa system and back every part with our comprehensive 1-year warranty. Orders ship same-day to get your spa running quickly. Before installation, verify your spa requires a 2-to-1 AX configuration and confirm the 6-pin connector matches your existing auxiliary connections for proper fitment.

Before you buy — quick checklist

  • Confirm your Balboa control board has an AX port that accepts a 6-pin connector
  • Verify your system requires a 2-to-1 split — not all Balboa boards support dual auxiliary outputs via Y-cable
  • Count the pins on your existing AX connector and match to this cable's 6-pin configuration
  • Check that both auxiliary devices you intend to run are compatible with a shared AX connection
  • Identify your Balboa board part number to confirm AX Y-cable compatibility before ordering

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
