The Spirax Sarco RTA-125 1/2" Angle Thermostatic Steam Trap is designed for efficient air and condensate removal in low-pressure steam heating systems. Its thermostatic operation automatically vents air and non-condensable gases during startup while closing tightly when steam reaches the trap, helping prevent live steam loss and improve overall system efficiency.

Featuring a compact angle-body design, the RTA-125 is ideal for steam radiator applications where a 90-degree connection configuration is required. Built with durable materials and engineered for reliable performance, this thermostatic radiator trap helps maintain balanced heating, reduce energy waste, and provide long-lasting service in residential, commercial, and institutional steam systems.
