Model L7618

Deflagration Flame Arrestor

The L7618 inhibits flame propagation in gas piping systems and protects low-pressure tanks containing flammable liquids. Use it to protect low-flashpoint liquids from external sources of ignition and increase fire protection and safety.

  • Unique recessed seating for superior protection
  • Quick and easy maintenance
  • Modular design allows easy and cost-effective flame-bank maintenance
  • Flame arrestor element geometry maximizes flame-quenching capability while minimizing pressure drop
  • Proven spiral-wound, crimped-ribbon flame element provides reliable protection

Flange sizes: 2″ – 12″

Standard housing materials: carbon steel, stainless steel, aluminum

Flame element: 316SS or aluminum – spiral-wound, crimped-ribbon

Operating temperature: <= 140°F (60°C)

Vertical installation only.
