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.
