About this seal/gasket

The Sundance Jacuzzi Pump Seal 6500-805 is an OEM replacement seal designed for Theramax pumps in Sundance spa systems. This precision-engineered seal features a 3/4" shaft diameter and 1-11/32" seal outer diameter, ensuring proper water containment and optimal pump performance in your spa.

Built to original equipment specifications, this genuine pump seal delivers the exact fit your Sundance spa requires. We guarantee precise fitment and back every seal with our comprehensive 1-year warranty. Most orders ship the same day for minimal downtime. When installing your new pump seal, ensure the pump is completely drained and disconnected from power before beginning work. Proper installation is critical for leak-free operation and maximum seal life.

Common symptoms this part fixes

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

  • Water leaking from beneath the pump
  • Wet motor housing or rust staining around the pump body
  • Pump shaft dripping during operation
  • Visible water trail from pump seal area
  • Pump running but losing prime due to seal failure

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

Before you buy — quick checklist

  • Confirm your pump is a Sundance Theramax model before ordering — check the pump label or existing seal markings
  • Verify shaft diameter is 3/4" on your existing pump
  • Verify seal outer diameter is 1-11/32" — measure the old seal if it is still in place
  • Inspect the pump impeller and shaft for scoring or corrosion before installing a new seal — a damaged shaft will destroy a new seal quickly
  • Check whether the leak is actually coming from the seal and not from a union fitting or plumbing connection

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