A fusible plug operates as a safety valve when dangerous temperatures, rather than dangerous pressures, are reached in a closed vessel. Fusible plugs are commonly installed in aircraft wheels, most typically in those of larger or high-performance aircraft.

Fusible link valves are also known as thermal shut-off valves. They are an automatic shut-off valve that cuts of any gas or liquid in the pipeline once a fire is present. For additional information regarding the product, please contact with dubuy support team.
