Product Overview

The Pentair 602274 1.5" IntelliVibe Nano Fitting Adapter – 5 Pack is a purpose-built accessory used when installing or retrofitting the IntelliVibe Nano LED light system into standard 1.5" return wall fittings. Pentair’s IntelliVibe Nano lighting system (2 W LED output) is designed for both underwater and above-water operation and usually installs via a dedicated niche or custom housing. However, for many retrofit cases, a conventional 1.5" return wall fitting is used. In these cases, the 602274 adapter is required, because the standard light assembly does not include this thread adapter.

Each adapter is threaded and designed to engage with the existing wall fitting, allowing the Nano light body to thread into it securely. When installing in a wet conduit environment, the adapter threads into the wall fitting hand‑tight (taking care not to over‑tighten) and acts as the mounting interface for the Nano luminaire itself. When retrofitting older or legacy niches, or when building new installations in tighter spaces, these adapters enable flexibility without needing full niche replacement.

Because these adapters are sold in a 5‑pack, installers or pool professionals can outfit multiple returns or keep spare adapters handy for maintenance or future upgrades. They are intended to provide a reliable, manufacturer‑approved interface between the standard 1.5" plumbing and the IntelliVibe Nano lighting units.

Use of the 602274 adapter must follow Pentair’s installation best practices, including proper sealing (O‑rings, thread tape, or gasket as per spec), clearance of debris in fittings, and avoidance of over‑torque to prevent damage to the light assembly or adapter. 

If you like, I can also prepare bullet‑point installation instructions or compatibility notes for different pool wall types (gunite, vinyl, fiberglass) using this adapter.
