Pentair 79200200 Sealing Ring – Standard 10-Hole Pattern

The Pentair 79200200 sealing ring is engineered for use in large stainless steel vinyl pool light niches featuring a 10-hole mount pattern. It provides a precise fit and reliable seal to maintain a watertight installation of the pool light housing and flange.

Key Features

  • Designed for large stainless steel light niches with standard 10-hole pattern.
  • Constructed of durable plated metal to maintain structural integrity in pool water environments.
  • Outer diameter approximately 12.25″; inner opening approximately 9.81″ for niche compatibility.
  • Replaces worn or corroded sealing rings to restore secure mounting and sealing of niche assembly.

Technical Details

  • Part Number: 79200200
  • Mount Pattern: 10 holes (standard configuration for large stainless steel niches)
  • Outer Diameter: ~12.25″
  • Inner Diameter: ~9.81″
  • Intended Application: Vinyl pool light niche ring/seal replacement

Installation & Compatibility Notes

Before installing, turn off power to the pool light circuit and drain water from the niche area if required. Remove the existing ring or plate, clean the niche flange and surrounding surface, and install the new sealing ring in alignment with the 10-hole pattern. Ensure all mounting screws or bolts are tightened evenly and the ring is seated flush to prevent leaks around the light assembly. After installation, verify the light housing is properly sealed and secure before restoring power.

Maintenance Tips

  • Inspect the sealing ring during each service interval for signs of corrosion, discoloration, or damage.
  • Replace mounting screws or hardware if they show signs of stripping, rust or wear to maintain proper seal integrity.
  • During pool resurfacing or light niche replacement, check that the sealing ring remains aligned and flush with the finished surface.
  • Ensure the niche gasket and ring are both in good condition to avoid leaks and to support safe underwater lighting operation.

Why Choose This Replacement Ring?

A sealing ring is a small but critical component in the light niche assembly. By replacing the 79200200 ring when the original has become pitted, distorted or otherwise compromised, you restore a proper watertight seal and reduce the risk of water intrusion or electrical hazards. For pool professionals and service techs, keeping the correct ring type in stock ensures efficient, safe lighting service and fewer callbacks.
