Spirax Sarco TSS-300 Steam Trap

The Spirax Sarco TSS-300 is a thermostatic steam trap with a 1/2 in NPT connection and a 300 psi rating, engineered to drain condensate from steam systems while releasing it near the saturated steam temperature. As part of Spirax Sarco’s thermostatic trap family, the TSS-300 uses a sensing element to open and close in response to condensate temperature, delivering reliable discharge without letting live steam pass. The trap can be installed in either horizontal or vertical piping, giving flexible mounting options in boiler rooms, heat exchangers, and steam distribution lines. This model is designed for use in demanding high-pressure steam applications, with installation and servicing guided by Spirax Sarco’s TSS-300 installation instructions to ensure proper venting, isolation, and accessibility. With standard NPT connections and compatibility with Spirax Sarco piping accessories, the TSS-300 provides straightforward integration into existing systems while maintaining condensate control and energy efficiency.
