Pentair AquaLuminator / Quasar Pool Light Gasket | 79116800

The Pentair 79116800 is a replacement light gasket used on select Pentair underwater pool/spa lighting systems. This gasket helps create a watertight seal between the light lens and housing to protect internal components from water intrusion and maintain safe, reliable operation.

Key Features

  • Watertight lens seal for compatible Pentair light assemblies.
  • Direct replacement for flattened, cracked, or hardened gaskets that can cause leaks.
  • Helps prevent moisture intrusion that can lead to fogging, corrosion, or light failure.

Compatibility

  • Pentair AquaLuminator pool and spa lights
  • Pentair Quasar pool and spa lights
  • Pentair CAL Color AquaLuminator pool and spa lights
  • Note: Some light assemblies may require two gaskets. Verify your light model’s parts diagram before ordering.

Specifications

  • Brand: Pentair
  • Part Number: 79116800
  • Catalog Reference: 3526-07
  • Approx. Dimensions: 6" L x 4" W x 3/4" H
  • Quantity: Sold individually

Common Reasons to Replace

  • Water in the lens area, moisture/fogging, or visible seepage at the light face
  • Gasket is brittle, flattened, cracked, swollen, or won’t seat evenly
  • Light has been opened for bulb/LED service and the old gasket cannot be reused reliably

Installation Notes

  • Turn off power at the breaker and follow all safety procedures for underwater lighting service.
  • Clean the lens and housing sealing surfaces thoroughly—old gasket residue can cause leaks.
  • Seat the gasket evenly without twisting or stretching.
  • Do not over-tighten the clamp ring/fasteners; tighten evenly to avoid distortion.
  • After reassembly, verify the seal before returning the light to normal operation.

Maintenance Tips

  • Replace the gasket any time the light is opened—reusing old gaskets is a common cause of leaks.
  • Keep sealing surfaces clean and free of grit to prevent pinched or uneven seals.
  • If moisture returns after gasket replacement, inspect the lens/housing for cracks or warping and replace damaged components.
