MODEL 7678

End-of-line Vertical – ATEX Certified

The 7678 model is an End-Of-Line Vertical Deflagration Flame Arrester designed to inhibit flame propagation in gas piping systems and to protect low pressure tanks containing flammable liquids. Arresters protect low flash point liquids from external sources of ignition. This provides increased fire protection and safety. • IEC gas group IIA (MESG > 0.90 mm)


  • Vertical installation only
  • Burn Time tBT 2 minutes (sizes 8”, 10” and 12”)*
  • Modular design allows easy and cost-effective flame bank maintenance
  • Flame arrester element geometry maximizes flame quenching capability while minimizing pressure drop
  • Proven spiral-wound, crimped-ribbon flame element provides reliable flame protection
