Pentair Pilot Screw with Captive Gum Washer, Brass | IntelliBrite Architectural Series | 79104800Z

OEM Replacement Fastener for Pentair Pool & Spa Light Assemblies

The Pentair Pilot Screw with Captive Gum Washer, Brass (79104800Z) is the OEM replacement fastener for Pentair IntelliBrite Architectural Series pool and spa light assemblies, as well as SpaBrite, AquaLight, and Amerlite lighting models.

IMPORTANT: LICENSED ELECTRICIAN REQUIRED
Pool lighting components operate in wet environments. Installation must comply with NEC Article 680 and be performed by a licensed electrician.

This brass pilot screw retains a captive gum washer — held in place on the screw shank so it cannot be lost during service — that maintains a proper seal at its point of installation within the light assembly. When the original screw is damaged, corroded, or the washer has deteriorated, this OEM replacement restores the fastener to factory specification.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before reinstalling or replacing this pilot screw, inspect the captive gum washer for compression set, cracking, or flattening. A washer that has taken a permanent set will not seal correctly regardless of torque applied — if there is any visible deformation, replace the entire screw assembly rather than reusing the old one. Always have a licensed electrician perform any work on pool or spa lighting. Pool lighting components operate in wet environments and installation must comply with NEC Article 680.
