Product Description

Flashback arrestors are designed to prevent reverse flow of oxygen and acetylene gases and thus the accidental mixing of the gases. Often used, and sometime required, in conjunction with torch end flashback arrestors for both upstream and downstream flashback prevention. Oxygen is standard right hand threads, acetylene is standard left hand threads. Fits most 1/4” and 3/16” twin hose sets.
