About this seal/gasket

This OEM heater gasket provides a reliable seal for Sundance Smart spa heaters, measuring 1-9/16" inner diameter by 2-15/16" outer diameter. Designed specifically for Sundance Spas systems, this genuine replacement gasket prevents water leaks and maintains proper heater operation. The precision-molded design ensures optimal sealing performance between heater components.

At Bubbles Supply, we guarantee an exact fit for your Sundance spa heater with our authentic OEM parts. Every gasket ships the same day when ordered before 2 PM EST and includes our comprehensive 1-year warranty for complete peace of mind. This gasket addresses common heater issues including overheating and operational failures. Always shut off power and allow the heater to cool completely before installation, and verify gasket dimensions match your existing seal for proper fit.

Common symptoms this part fixes

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

  • Water leaking from heater assembly
  • Wet equipment bay with no obvious source
  • Heater shutting off due to moisture intrusion
  • OH or HH error codes triggered by heater seal failure
  • Visible mineral deposits or corrosion around heater flange

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

Before you buy — quick checklist

  • Measure your existing gasket — confirm 1-9/16" ID and 2-15/16" OD before ordering
  • Verify your spa uses a Sundance Smart heater assembly, not a standard inline heater
  • Inspect the heater tube flange for cracks or corrosion — a new gasket won't seal against a damaged seating surface
  • Check whether the leak is at the gasket face or at the union fittings — different repair

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

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