The coupler assembly connects and seals adjacent components within the heater's fuel or airflow circuit, transferring media between sections of the system while maintaining a leak-free, pressure-stable joint. In a flameless air heater, this type of connection is critical to consistent burner performance and safe, efficient heat output. When a coupler assembly wears, cracks, or loses its sealing capability, the heater may run inefficiently, produce inconsistent heat, or fail to operate safely — making timely replacement essential.
