Xylem-Hoffman Specialty 404270 3/4″ NPT 15 PSI Cast Iron Float & Thermostatic Steam Trap FT015I-3

Description

Overview

The Xylem-Hoffman Specialty FT015I-3 (SKU 404270) is a Series I Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable, continuous condensate drainage in low-pressure steam heating and process systems. Combining a float mechanism for continuous liquid discharge with an integral thermostatic air vent for automatic air and non-condensable gas elimination, this trap delivers efficient steam system performance and helps prevent waterlogging and energy waste.

Key Features

• Float & Thermostatic (F&T) design provides continuous condensate removal and automatic air venting in a single unit
• 3/4″ NPT connections for straightforward installation into standard piping configurations
• Rated for 15 PSI maximum operating pressure — ideal for low-pressure steam heating systems
• .253″ orifice diameter sized for optimal condensate flow at rated pressure
• Integral thermostatic air vent automatically purges air and non-condensable gases on system startup and during operation
• Cast iron body construction (Series I) offers durability and long service life in commercial and industrial environments
• Compact design simplifies installation in tight mechanical spaces
