Description
Overview
The Xylem-Hoffman Specialty 404200 (Model FT015H-3) is a Series H Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable condensate removal and air venting in low-pressure steam heating systems. Combining a float-operated discharge mechanism with an integrated thermostatic air vent, this trap continuously drains condensate at steam temperature while automatically purging non-condensable gases — keeping your steam system operating at peak efficiency.
Key Features
- Series H Cast Iron body construction for durability in demanding steam system environments
- 3/4″ NPT connections for straightforward installation into standard piping
- 15 PSI maximum operating pressure rating
- .253″ orifice for precise, calibrated condensate discharge
- Integrated thermostatic air vent automatically purges air and non-condensable gases on startup and during operation
- Float-operated mechanism provides continuous, modulating condensate drainage at steam temperature
- Compact design suitable for unit heaters, heat exchangers, radiators, and other low-pressure steam heating equipment

Why Choose Hoffman Specialty F&T Traps?
Hoffman Specialty has been a trusted name in steam system components for decades. The Series H Float & Thermostatic design delivers continuous condensate removal without backing up into the heat transfer surface, maximizing system efficiency and preventing water hammer. The built-in thermostatic air vent ensures rapid system warm-up and eliminates air binding — two of the most common causes of poor steam system performance.
