Spirax Sarco FTI-75 Float and Thermostatic Steam Trap

The Spirax Sarco FTI-75 Float & Thermostatic Steam Trap is a cast-iron, 1/2-in. NPT float-and-thermostatic trap designed to continuously discharge condensate at steam temperature while venting non-condensables through an internal balanced-pressure air vent. The float mechanism modulates to discharge condensate as it forms, helping prevent water hammer and maintain efficient heat transfer, while the built-in air vent handles non-condensable gases. This model is rated for up to 75 psig steam service and is configured for inline, straight-through installation with 1/2 in. NPT connections. Built with a durable cast-iron body, it suits HVAC and process applications such as heating coils, steam tracing, and shell-and-tube heat exchangers where reliable condensate drainage is essential.
