About this seal/gasket

The Sundance Spas Light Lens O-Ring 6541-000 creates a watertight seal between your spa's light lens and housing assembly. This genuine OEM replacement part fits Sundance spa lighting systems, preventing water infiltration that can damage electrical components and compromise safety.

Manufactured with durable BUNA rubber construction, this precision o-ring features a 1/16" cross-section and 5/16" outer diameter for exact specifications. At Bubbles Supply, we guarantee this is the exact fit your Sundance spa requires, backed by our 1-year warranty and same-day shipping on in-stock items. Whether you're performing routine maintenance or replacing a damaged seal, this OEM part ensures your spa lighting operates safely and reliably. Always inspect the o-ring groove for debris and apply a thin coat of silicone lubricant during installation for optimal sealing performance.

Common symptoms this part fixes

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

  • Water leaking around spa light lens
  • Light housing filling with water
  • Corrosion or moisture visible inside light assembly
  • Light flickering or failing due to water intrusion
  • Visibly cracked, flattened, or brittle o-ring on light lens

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

Before you buy — quick checklist

  • Confirm your spa is a Sundance brand — this is an OEM part and fitment is brand-specific
  • Verify the o-ring groove dimensions match: 1/16" cross-section and 5/16" outer diameter
  • Inspect the light lens housing for cracks or damage — a new o-ring won't seal a cracked housing
  • Check the o-ring groove for debris, scale buildup, or corrosion before installing
  • Have silicone-based lubricant on hand — do not use petroleum-based grease, which can degrade BUNA rubber

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