Tri-Lobe O-Ring for Nature2® Fusion
Product Overview
The exact OEM collar seal pool techs use to prevent pressure leaks on Nature2 Fusion sanitizers.
Designed specifically for Jandy Nature2 Fusion and Fusion Soft inground mineral sanitizers, this genuine OEM tri-lobe collar O-ring creates a watertight pressure seal around the vessel lid. The custom three-lobed profile seats evenly within the collar groove, eliminating the rolling and pinching common with standard round seals during cartridge changes.

When To Use This
Pro Tip
Always wipe the collar threads and O-ring groove clean with a microfiber cloth before installing the new seal; even a single grain of sand in the channel can compromise the pressure seal.
Common Questions & Instructions
How often should the Nature2 Fusion tri-lobe O-ring be replaced?
In our experience, pool techs replace this seal every 12 to 24 months, or whenever changing the mineral cartridge if the rubber shows signs of flattening, stiffness, or cracking.
Can I replace the tri-lobe O-ring with a standard circular O-ring?
No. Standard round cross-section O-rings will bunch up and pinch when tightening the locking collar, which creates leaks and risks cracking the threaded collar housing.
What type of lubricant should be used on this Nature2 O-ring?
Apply a thin film of silicone- or PTFE-based pool lubricant. Never use petroleum-based lubricants like Vaseline, as petroleum breaks down the elastomer and causes swelling.
