What is a flashback ?
A flashback is an ignition of mised gases in an oxy-fuel cutting and welding system.

Are flashback arrestors and check valves the same ?
No.  A check valve stops the reverse flow of gas;  a flashback arrestor extinguishes a flashback fire.  Smith's flashback arrestor with built-in check valve does both.

Why do I need a flashback arrestor ?
Mixed gas explosions and flashback fires can result in damage to equipment and / or servere personal injury or death.  Smith flashback arrestors with built-in check valves help prevent accidents caused by the reverse flow of gases and flashback fires.
