Pentair 79108600z Silicone Gasket 4 in White Aqualight

Product Description

The PENTAIR 79108600z is a 4-inch white silicone gasket designed as a direct replacement component for AquaLight pool and spa light fixtures. This gasket creates a watertight seal between the light lens and the fixture housing, preventing water intrusion and protecting electrical components from moisture. Fabricated from durable silicone, it resists degradation from pool chemicals, UV exposure, and continuous submersion. Pool and spa service technicians install this gasket during routine light maintenance or when addressing light housing leaks.

This gasket is intended for use with Pentair AquaLight pool and spa light fixtures rated at 100 watts or 250 watts. It is suited for residential and commercial in-ground pool and spa installations where AquaLight fixtures are in service. The white color is consistent with standard AquaLight fixture aesthetics. Replacement is typically performed when the existing gasket shows signs of compression set, cracking, or leaking around the lens assembly.

Installation Notes

Installation should be performed by a licensed pool and spa service technician. Before servicing any pool light fixture, shut off all electrical power to the circuit at the breaker panel and verify the circuit is de-energized with an appropriate testing device. Inspect the gasket seating surface on the fixture housing for debris or damage before seating the new gasket. All underwater light repairs must comply with applicable local electrical codes and NEC Article 680 requirements.
