The Pentair 172855 Air Vent Strainer is a factory-original 3/4-inch stainless steel component engineered for Pentair Nautilus Plus and FNS D.E. pool and spa filter systems. This strainer functions as a protective screen that blocks debris from entering the air valve tube, shielding delicate internal parts and preserving peak filtration performance. Its stainless steel construction delivers outstanding resistance to corrosion, even under prolonged contact with chlorinated water and elevated system pressures. By keeping the air relief pathway clear and unobstructed, the strainer promotes stable system operation and reliable pressure management. Designed as a direct drop-in replacement, it installs quickly and keeps your filter running at its best.

Key Benefits

• Corrosion-Resistant Construction: Made from 3/4-inch stainless steel, the Pentair 172855 delivers superior longevity and withstands chemical and environmental wear common in pool and spa settings.
• Protects Air Valve Tube: Serves as a frontline barrier against debris intrusion, safeguarding the air valve tube from clogs that can disrupt airflow and compromise filtration efficiency.
• Maintains Uninterrupted Air Flow: Keeps the air relief vent free from blockages, enabling proper pressure venting and balanced hydraulic operation throughout the entire filter system.
• OEM-Designed Fit: Precisely manufactured for Pentair Nautilus Plus and FNS series filters, this strainer drops into place without any modifications, simplifying replacement and routine upkeep.
