Fusible plug

Definition and use

The fusible plug is a waterproof plug linking the inside and the outside of a box, containing for example reactive products.


We manufacture fusible plugs which aims to melt when the temperature inside the box reaches a specific temperature. These plugs melt and thus prevent explosion of the container caused by pressure increase.




Features :

We offer a large panel of fusible alloy and eutectic alloy from 20°C to 200°C adapting to specific needs.


These metallic fusible plugs are made of steel with a low melting point alloy : eutectic, single phase, binary or ternary.


The use of a DSC (Differential Scanning Calorimetry) is a guarantee for the melting point of these thermal stoppers.
