Description
A semicircular, scored, reverse-acting rupture disc with precise failure-initiating indentations that allow reversal at low burst pressures.
The patented asymmetric failure-initiating indentations, high-precision scoring and a variety of construction materials make the MINTRX rupture disc a versatile, cost-effective choice for overpressure protection. MINTRX burst pressures are in the mid-range of the RX line of scored, reverse-acting rupture discs.
Precision failure-initiating indent, high-precision scoring and a variety of construction materials make the MINTRX rupture disc a versatile and economical overpressure protection option.
MINTRX burst pressures are in the mid-range of the TRX line of scored, reverse-acting rupture discs. Learn more about the ULTRX, for high-pressure applications, or the STAR X, for ultra low-pressure applications.

The MINTRX rupture disc is a low-pressure, scored, reverse-acting rupture disc that acts as a non-reclosing differential pressure relief device, protecting equipment, vessels and systems from overpressure damage. It is also excellent for safely isolating pressure relief valves.
The MINTRX features a non-fragmenting design with uniform petal-opening flow characteristics.
The MINTRX is designed with a standard manufacturing range of zero. This allows the system to operate up to 90% of the disc's specified burst pressure. Every rupture disc undergoes fail-safe pressure testing at 90% of the specified rating before shipment.
Innovative encapsulating rings
Our encapsulating rings prevent overtightening from affecting the burst accuracy of the MINTRX. They also:
Hold the rupture disc in the proper position.
Prevent the disc from slipping when insufficient bolt load is applied to the mating flanges.
Make installation easier.
No vacuum support needed
The MINTRX withstands full vacuum without affecting burst pressure setting or reliability. No additional components, such as a vacuum support, are required, which means lower cost and fewer worries for you.
Corrosive application? No problem.
The MINTRX performs well in corrosive media environments. The versatile material selection and the use of thicker materials contribute to exceptional corrosion resistance. A fluoropolymer coating can be used on the process side for additional corrosion protection.
