    Rupture Plugs for Extrusion Applications Rupture plugs are designed for reliable emergency relief of excess pressure since they instantaneously rupture at a specific predetermined pressure range. Dynisco's model BP420 rupture plug is designed specifically for use in plastic extruders. Each assembly consists of a stainless steel body and rupture disk. A rupture plug may be specified for primary relief in applications where pressure buildup can occur so rapidly that the response time of a relief valve is inadequate, such as in a polymerization reaction vessel.

    Simple, intrinsically safe design
    Leak - tight seal
    Low installation and maintenance cost
    Up to 750°F melt temperatures
    Accuracy of ±5%
