The Pentair Lens with O-Ring (590104Z) is the OEM replacement lens assembly for the ColorVision LED Light Bubbler, restoring full light output and a watertight seal to your water feature. ⚠️ IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY Always lubricate the included O-ring with a silicone-based lubricant before installation. We carry the Pentair R172351 Lifeguard® Silicone Lubricant — the OEM-matched product for Pentair equipment. The lens protects the ColorVision LED light module from water intrusion while transmitting the full spectrum of color output. The included O-ring provides the compression seal between the lens and the bubbler housing. A cracked, clouded, or leaking lens will compromise both light performance and the integrity of the light chamber — replacing the lens and O-ring together as a unit ensures a complete, reliable repair.

Pro Tip Before seating the new lens, apply a thin, even coat of Pentair R172351 Lifeguard® Silicone Lubricant to the O-ring. This helps the O-ring seat evenly in the groove, prevents tearing during assembly, and extends seal life. Never use petroleum-based lubricants — they will degrade the O-ring and cause premature seal failure.
