WMP Welded Muffled Plug Rupture Disc Assembly

Protect equipment, personnel and the environment with the threaded, single-use WMP Welded Muffled Plug rupture disc assembly. The WMP is ideal for applications that discharge to the atmosphere at the rupture disc.

The WMP is a solid-metal, tension-acting rupture disc that screws directly into a threaded port, providing precise overpressure protection with minimal installation time.

WMP Welded Muffled Plug Rupture Disc Assembly

The rupture disc is welded to a threaded outlet body and inlet ring, creating a bubble-tight seal between the rupture disc, outlet body and inlet ring. Six holes in the outlet body’s hexagonal head reduce reaction forces after the rupture disc has burst.

We supply the highly versatile WMP in a wide range of burst pressures and temperatures for applications in dozens of industries, including:

Hydraulic Systems

  • Actuators
  • Accumulators
  • Pumps
  • A/C systems
  • Braking systems
