Pentair Small Stainless Steel Light Niche, 1" Rear Hub (Vinyl/Fiberglass) | 78242300

The Pentair 78242300 is a small stainless steel light niche designed for vinyl liner and fiberglass pool/spa installations.

Key Features

  • 1" rear hub connection for conduit routing from the niche to the junction box.
  • Made for vinyl/fiberglass walls (commonly used in manufactured pools, spas, and hot tubs).
  • Provides a clean, recessed mounting point for compatible small underwater light fixtures.
  • Service-friendly installation for new builds, retrofits, and remodels when a niche is required.

Compatibility

  • Application: Vinyl liner and fiberglass pool/spa walls
  • Use With: Compatible Pentair small light fixtures that require a small niche housing (match your light model and niche style)
  • Tip: Confirm your light type (small niche vs. large niche vs. nicheless) before ordering.

Maintenance Tips

  • If the light is opened for service, replace the sealing gasket(s) to reduce the risk of moisture intrusion.
  • Keep chemical balance in range—aggressive water can accelerate corrosion on metal components over time.
  • If you notice moisture behind the lens or repeated GFCI trips, shut off power and have the system inspected immediately.
