About this union/fitting

The Aqua-Flo by Gecko 2" FBT x 2" S Union Complete (Part #52272000) is an essential pump connection component designed for Aqua-Flo main pump systems. This OEM union assembly features a 2-inch female buttress thread (FBT) connection on one end and a 2-inch slip (S) connection on the other, creating a secure, watertight seal between your pump and plumbing.

Built to Aqua-Flo's exacting standards, this union complete includes all necessary components for a professional installation. At Bubbles Supply, we guarantee an exact fit with your existing pump setup, backed by our comprehensive 1-year warranty and same-day shipping on in-stock items. The DR-compatible design ensures reliable performance and easy maintenance access when pump service is required. Always verify your existing union measurements and thread types before ordering to ensure proper fitment with your spa's plumbing configuration.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Water leaking at pump union connection
  • Union cracked or visibly damaged
  • Union threads stripped or cross-threaded
  • Union O-ring failure causing slow drip or weeping leak
  • Unable to disconnect pump for service due to damaged union body

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing union is 2-inch FBT on the pump side — buttress thread is not the same as standard NPT
  • Verify the plumbing side is 2-inch slip (S), not threaded
  • Inspect the full union assembly — if the tail piece or O-ring is damaged, this complete kit covers all components
  • Confirm your pump is an Aqua-Flo model — this is an OEM part and thread profiles must match exactly
  • Check whether your spa uses a DR-style union configuration before ordering

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