The Swimables SW-26-855 Air Vent Strainer is a precision replacement for Pentair part number 172855, built specifically for Pentair FNS, Nautilus, and Nautilus Plus D.E. filters. This component serves a dual purpose: it provides a clear pathway for trapped air to vent from the filter tank while simultaneously screening out debris that could obstruct the air relief mechanism. Crafted from corrosion-resistant materials designed to endure constant exposure to water and pool chemicals, the SW-26-855 helps maintain proper pressure equilibrium and smooth water circulation throughout your D.E. filtration system.

Key Benefits

• Pentair 172855 Replacement: Designed as an exact substitute for the OEM part, fitting FNS, Nautilus, and Nautilus Plus D.E. filters without any adaptation needed.
• Dual-Action Air Relief: Vents trapped air from the filter tank while filtering out particles that could block the relief system.
