About this seal/gasket

This 5-7/8" ID x 6" OD O-Ring (part #6500-605) provides a reliable seal for Sundance Spas housing components featuring LX 56-frame pumps. Engineered to OEM specifications, this critical seal prevents water leaks and maintains proper system pressure in your spa's pump housing assembly.

Common symptoms this part fixes

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

  • Water leaking from pump housing or volute seam
  • Wet spot under pump with no visible cracked plumbing
  • Loss of system pressure at jets
  • Air entrainment or gurgling caused by housing seal failure
  • Visible deterioration, flattening, or cracking of existing o-ring

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

Before you buy — quick checklist

  • Measure your existing o-ring — confirm 5-7/8" ID and 6" OD before ordering
  • Verify your pump uses an LX 56-frame motor configuration
  • Inspect the o-ring groove in the pump housing for cracks or scoring that may prevent proper sealing
  • Check whether the leak is at the housing seam versus a union or fitting — this o-ring only addresses the housing seal
  • Have your spa's service manual on hand to confirm part number cross-reference for your specific model year

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