Before you buy — quick checklist

  • Confirm your heater housing accepts a 2-inch slip connection on the plumbing side
  • Verify your existing tailpiece uses 2-inch male buttress threads (MBT) — not standard NPT or other thread types
  • Check that your heater housing has no O-ring groove — this tailpiece is designed for a no O-ring groove application
  • Inspect the mating heater housing for damage before installing a new tailpiece
  • Confirm this is a Magic Plastics OEM application if matching to a specific heater brand

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