Xylem 404208 Hoffman FT175H-3 Float & Thermostatic Steam Trap 3/4" NPT 175 PSI

The Xylem-Hoffman Specialty 404208 is a Series H float and thermostatic (F&T) steam trap designed for continuous condensate drainage in steam heating and process systems. This heavy-duty cast iron trap features a 3/4" NPT connection size and is rated for 175 PSI maximum operating pressure with a maximum temperature of 406°F.

Key Features:

• Model FT175H-3 with 3/4" NPT pipe connection
• 175 PSI maximum steam operating pressure, 250 PSI body design pressure
• Condensate capacity of 1,190 pounds per hour
• Universal 4-port H-pattern tappings (2 inlets, 2 outlets) for flexible piping configurations
• Stainless steel internal components for corrosion resistance
• Below-condensate seat design prevents steam leakage
• Rugged thermostatic air vent element eliminates air binding
• Cast iron construction for durability

Applications:

• Heat exchange equipment requiring rapid air and non-condensable gas venting
• Modulating steam pressure systems with widely varying loads
• Low to high pressure steam mains
• Systems with pressures ranging from maximum to vacuum conditions

The Series H float and thermostatic trap excels at venting air at very low pressures, handling startup air loads, operating against back pressure, and providing continuous condensate drainage. The H-pattern configuration allows steam to enter from either side and condensate to discharge from the opposite or same side, with unused ports sealed using standard pipe plugs.
