About this seal/gasket

This 1.5" Deco Lens Gasket (part #400-39) is an OEM replacement seal designed specifically for Dimension One Spas lighting systems. This gasket creates a watertight seal between the 1.5-inch decorative lens and the spa shell, preventing water infiltration that could damage electrical components or compromise your spa's lighting performance.

Manufactured to Dimension One's exact specifications, this genuine gasket ensures perfect fitment and reliable sealing for years of trouble-free operation. At Bubbles Supply, we guarantee an exact fit for your spa, back every part with our comprehensive 1-year warranty, and ship same-day to get your lighting back to full brightness fast. When installing, ensure all surfaces are clean and free of old gasket material for optimal seal integrity.

Before you buy — quick checklist

  • Confirm your spa is a Dimension One brand — this is an OEM-specific part
  • Verify the lens opening in your spa shell measures 1.5 inches
  • Inspect the existing gasket for deformation or tearing to confirm it is the source of the leak
  • Check that the lens itself is not cracked — a new gasket won't seal against a damaged lens
  • Have the part number 400-39 confirmed against your spa's parts manual before ordering

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