Light your torch safely...eliminate the dangerous use of matches and butane lighters

A flashback is a momentary or sustained retrogression of the flame upstream of the mixer usually in the torch or hoses. This is a potentially hazardous situation, particularly if the flame reaches the hoses, where an explosion may result causing a rupture or separation of the hose. A flashback (flame) arrestor is a device that helps prevent the propagation of a flame upstream. Note that this device reduces the volume of gases available at the tip/nozzle. Series RFA & TFA arrestors have inlet filters to prevent dust, dirt and other contaminants larger than 100 microns from entering the system, thus providing longer unit service. Series TFANF and RFANF arrestors do not have filters, but will still extinguish flashbacks while providing initial cost savings.
