WITT RF Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks in accordance with DIN EN ISO 5175-1. Every Arrestor 100% tested.

The best Flashback Arrestors in the world

  • a large surface area flame arrestor FA of stainless steel construction extinguishes any dangerous flashback entering the device in any direction
  • a temperature-sensitive cut-off valve TV extinguishes sustained flashbacks long before the internal temperature of the arrestors reaches a dangerous level
  • a spring-loaded non-return valve NV prevents slow or sudden reverse gas flow from forming explosive mixtures in the gas supply
  • a filter at the gas inlet protects the arrestor against dirt contamination, extending the service life
  • a pressure relief valve vents excessive pressure and soot into the atmosphere, protecting the hose from bursting and the flame arrestor from clogging up, thus maintaining the flow rate

Operation / Usage:

  • RF Flashback Arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks
  • for pipeline outlets and single cylinders
  • WITT Flashback Arrestors may be mounted in any position / orientation
  • only one piece of equipment may be connected to a single Flashback Arrestor
  • the maximum ambient / working temperature is 60 °C / 140 °F
  • gases: acetylene, town gas, natural gas, LPG, hydrogen, oxygen, compressed air (more upon request)


  • annual testing of the check valve, body leak-tightness and flow capacity is recommended
  • WITT is happy to supply special test equipment
  • Flashback Arrestors are only to be serviced by the manufacturer; the dirt filter may be replaced by competent staff
