Regulator end flashback arrestors are
safety devices fitted to the outlet of a regulator. They
incorporate a number of features designed to protect upstream
equipment from damage in the event of a flashback or sustained burn
back. Of importance, all regulator end models incorporate a thermal
cut-off valve as a failsafe, to shut off the flow of gas,
eliminating the fire.

The DGNDK model flashback arrestor
offers all of the functionality of the DGN standard flow model,
with the addition of a quick action coupling and pin. The pin
connects to the hose while the flashback arrestor remains on the
regulator. The hose can then be connected to the flashback arrestor
via the coupling pin. This allows for quick connection and
disconnection of the hose without the need for spanners. The
coupling and pin meet ISO 7289 and the double 'O' ring design
ensures no leakage. Also different coupling pins are available as spare parts for
regulator end flashback arrestors.

The DS1000 model flashback arrestor
offers all of the functionality of the DGN standard flow model,
with the additional resettable pressure sensitive cut-off valve
