Pentair Lens Seal – Model 78880200

The Pentair 78880200 is the OEM silicone lens seal designed for use with the AquaLumin and AquaLumin II pool/spa lights. It creates a watertight barrier around the light lens to prevent leaks and maintain safe underwater lighting.

Key Features:

  • Genuine Pentair replacement part for AquaLumin/AquaLumin II light assemblies
  • Silicone‑rubber material engineered to resist pool chemicals and UV exposure
  • Precisely molded shape ensures proper fit and consistent seal performance

Technical Specifications:

  • Model / SKU: 78880200
  • Application: Lens seal for Pentair AquaLumin/AquaLumin II lights
  • Material: Silicone rubber, white color
  • Typical dimensions: Outside diameter ~7½″, inside diameter ~6¾″, thickness variable (~¼″ one side, ~⅛″ on other) — check fit during installation.
  • Included: One (1) lens seal only (light and other parts sold separately)

Maintenance Tip: Whenever you remove the light face ring or replace the bulb, inspect this seal for flattening, cracks or deformation. Clean the sealing surface thoroughly, apply a thin coat of pool‑safe silicone grease, and ensure the seal seats evenly before reassembling the face ring. Proper sealing prevents lens leaks, electrical failure, and potential water intrusion.
