Xylem 401542 17C Angle Thermostatic Steam Trap with Short Nipple

The Xylem 401542 is a 1/2-inch balanced pressure thermostatic steam trap featuring an angle pattern with short nipple connection. Part of the Hoffman Specialty Bear Trap series, this cast bronze steam trap is designed for institutional, commercial, and residential heating system applications where reliable condensate removal is essential.

Key Features:

• 1/2-inch NPT threaded connection with angle pattern and short nipple configuration
• Balanced pressure thermostatic element with stainless steel bellows diaphragm
• Cast bronze construction for durability and corrosion resistance
• 25 PSI maximum operating pressure rating
• 880 pounds per hour condensate capacity
• Subcooling capability for efficient system operation and elimination of flash steam losses

The thermostatic element expands when steam is present to close the trap, and contracts when cooler air or condensate is present to open the trap and allow drainage. This balanced pressure design reduces system start-up times and improves overall heating efficiency. Ideal for schools, hospitals, apartment buildings, and residential applications where low to moderate water hammer may occur.
