    Heat-Activated Threaded Pressure-Relief Discs

    Image of Product. Front orientation. Pressure-Relief Discs. Heat-Activated Threaded Pressure-Relief Discs.
    Also known as fusible plugs, these discs have a metal core that melts at a set temperature to exhaust discharge directly and allow unrestricted flow. Install these one-time-use discs in pipelines and tanks.
    500 psi Maximum Pressure—These discs should not be used in a system with an operating pressure greater than 500 psi.
    Maximum Operating Temperature—Exceeding the maximum operating temperature decreases service life and may cause the disc to open below its melting temperature.
