Frequently asked questions

What is a resettable flashback arrestor?

It is a safety device that stops a flashback from travelling back up the gas line. The resettable collar type clearly indicates when a flashback has occurred and can be manually reset afterwards via the collar.

Which gases is it for?

This arrestor is designed for oxygen and acetylene use.

Why choose the resettable collar type?

It provides the highest possible level of long-term protection and will withstand a series of flashbacks, then be reset rather than replaced, making it a durable choice for regular use.

Will it trip from external heat?

No. It reacts to a flashback but will not react as a consequence of external heat, so it is not triggered by nearby heat sources.

What happens after a flashback?

The device clearly indicates that a flashback has occurred, and you manually reset it via its collar before continuing work.
