8 3/8" Lens Gasket for Amerlite Incandescent Underwater Pool Lights
Product Overview
Pool technicians reach for the Pentair 79101600Z whenever an Amerlite fixture is opened to ensure a watertight seal.
This 8 3/8-inch gasket is the standard specification for Pentair Amerlite incandescent underwater pool lights. Unlike generic rubber alternatives that may degrade prematurely under high heat and chemical exposure, this genuine Pentair 79101600Z part maintains its elasticity to prevent water intrusion into the light niche. In our experience, replacing the gasket every time the bulb is changed is the most reliable way to avoid costly fixture failures and electrical shorts.
Benefits & What Makes It Different
Genuine Pentair 79101600Z
Using the OEM part ensures exact fitment for the 8 3/8-inch lens, preventing the leaks often caused by slightly off-spec generic gaskets.
High-Temp Resistance
Designed specifically for incandescent fixtures, this gasket handles the high operating temperatures of 300W to 500W bulbs without hardening or cracking.
Watertight Compression Seal
The profile of this gasket is engineered to compress evenly against the Amerlite housing, creating a barrier that protects the electrical socket from corrosion.
Compatibility
- Pentair Amerlite Incandescent Series
- 8-3/8 inch diameter lenses
- Standard 12V and 120V Amerlite housings
When To Use This
Pro Tip
When tightening the pilot screw on the light clamp, don't over-torque it; instead, ensure the clamp is seated evenly around the entire circumference of the gasket to maintain a uniform seal.
Common Questions & Instructions
How often should I replace the Pentair Amerlite lens gasket?
We recommend replacing the 79101600Z gasket every time you open the light fixture to change a bulb. Reusing an old, compressed gasket significantly increases the risk of water leaking into the housing and shorting out the light.
Will this gasket fit the Pentair IntelliBrite LED pool lights?
No, this 8 3/8-inch gasket is specifically designed for the Amerlite incandescent series. LED fixtures like the IntelliBrite use a different gasket profile, so verify your light model number before ordering to ensure a proper seal.
Do I need to use silicone lubricant on this pool light gasket?
While not strictly required, applying a light coating of a pool-grade silicone lubricant can help the gasket seat properly and prevent it from pinching or binding during the reassembly of the stainless steel clamp.
