About this seal/gasket

This HydroQuip heater gasket delivers the precise seal your spa's heating system needs to operate safely and efficiently. With its 3-7/16" inner diameter and 4-7/16" outer diameter, this OEM gasket fits HydroQuip heater assemblies and provides a reliable barrier against water leaks at the heater end cap connection.

Engineered to HydroQuip's exact specifications, this gasket restores your heater's original performance while preventing costly water damage to electrical components. At Bubbles Supply, we guarantee an exact fit with same-day shipping and back every gasket with our comprehensive 1-year warranty. When replacing this gasket, always inspect the heater end cap surface for damage and ensure proper torque specifications to achieve optimal seal performance.

Common symptoms this part fixes

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

  • Water dripping or pooling at heater end cap
  • Heater tripping due to moisture near electrical components
  • Visible mineral deposits or crust around heater tube seam
  • Soft or deformed original gasket that no longer seats properly
  • Slow drip that worsens when heater cycles on and activates pressure

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

Before you buy — quick checklist

  • Measure your existing gasket — confirm 3-7/16" ID and 4-7/16" OD before ordering
  • Verify your heater assembly is a HydroQuip unit — check the heater label or control system brand
  • Inspect the heater end cap seating surface for cracks, pitting, or corrosion before installing a new gasket
  • Do not reuse the old gasket — even if it looks intact, a used gasket will not reseal reliably
  • Have a towel and small catch bucket ready — residual water will drain when you open the heater

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