Common symptoms this part fixes

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

  • Water leaking at heater union connection
  • Cracked or broken heater tailpiece
  • Stripped buttress threads causing persistent leak
  • O-ring groove damaged, preventing seal
  • Heater union weeping after tightening

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

Before you buy — quick checklist

  • Confirm your existing tailpiece uses 2" male buttress thread — not all heater unions use buttress thread profiles
  • Verify the slip side of your plumbing is 2" nominal pipe
  • Inspect the mating union nut for damage before reinstalling — a damaged nut will cause leaks even with a new tailpiece
  • Check whether your heater assembly uses one or two tailpieces so you order the correct quantity
  • Confirm this is a Magic Plastics OEM part number matching what's currently installed

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

Install difficulty: Medium — Some experience neededTypically 30–60 minutes
