- 400-4 Automatic Float Air Vent for Hydronic Heating - Direct replacement for Taco 400-4 Hy-Vent. Fits 1/8" NPT ports on boiler expansion tanks, radiators, baseboards, and radiant panels. Releases trapped air automatically.
- Eliminates Airlocks & Radiator Gurgling - Float mechanism opens to vent trapped air, then seals when water arrives. Prevents air pockets that reduce heating efficiency, cause cold spots, and create noisy pipe gurgling.
- Solid Brass Body, 150 PSI & 240°F Rated - Durable brass construction withstands high-pressure, high-temperature boiler environments. Resists corrosion and mineral buildup better than plastic vents that crack or peel.
- Serviceable Cleanable Top Cap - Unlike sealed vents that must be replaced when fouled, the threaded cap unscrews for easy cleaning of mineral deposits and debris. Clean and reassemble to restore full venting performance.
- Easy DIY Installation - No plumber needed. Apply Teflon tape to 1/8" NPT threads and hand-tighten onto your boiler expansion tank or radiator port. Most installations complete in under 10 minutes with basic tools.
