Hoffman Specialty 404210 Steam Trap

The Hoffman Specialty 404210 (Model FT015H-4) is a heavy-duty Series H Float and Thermostatic Steam Trap engineered for efficient condensate drainage and air venting in low-pressure steam systems. This 1" NPT steam trap is built with a rugged cast iron body and features a .253" orifice designed specifically for a 15 PSI seat differential pressure. For technicians performing system retrofits or maintenance, the 404210 serves as the direct replacement for the legacy IFT-15-1 and part number 0037105.

Designed for continuous modulating loads, this F&T trap utilizes a 4-port piping configuration to provide maximum installation flexibility in tight mechanical rooms. The internal stainless steel components—including the float, valve pin, and seat—provide superior resistance to water hammer and corrosion. A key technical feature is the balanced pressure thermostatic air vent, which actively eliminates air binding to ensure rapid system start-ups. With a maximum body design pressure of 250 PSIG and a temperature rating of 406°F, this unit is the standard for steam main drips and unit heater applications.

• Universal Piping: The 4-port design (two inlets, two outlets) simplifies 1-inch NPT connections and allows for easy system monitoring.
• In-Line Serviceability: The trap cover assembly can be removed and serviced without disturbing existing piping, reducing labor time for contractors.
• High Condensate Capacity: Efficiently handles 1,600 lbs/hr of condensate at a 15 PSI differential, ensuring dry steam lines.
• Air Binding Prevention: The integrated thermostatic element ruggedly handles non-condensable gases even at very low pressures.

What is the difference between the FT015H-4 and an inverted bucket trap?
Unlike bucket traps, the Hoffman FT015H-4 provides continuous drainage and immediate air venting, making it better suited for modulating steam pressures and equipment where air removal is critical during start-up.

Can I use this trap on a high-pressure steam line?
While the body design can withstand higher pressures, the orifice in the 404210 is optimized for a 15 PSI maximum seat differential. Exceeding this pressure may prevent the trap from opening against the system head.

Is the 404210 compatible with older IFT-15-1 units?
Yes, this model is the direct technical replacement for the IFT-15-1 and 0037105, maintaining the same 1-inch pipe sizing and performance characteristics.
