## Overview

The RX Weld Oxygen Acetylene Flashback Arrestors Set features high-quality brass construction and standard 'B' 9/16-18 UNF fittings, designed to prevent dangerous flashbacks by allowing gas flow in only one direction. Compatible with acetylene, propane, and Mapp gas, this essential safety device ensures your welding setup stays secure and reliable under pressures up to 290 PSI for oxygen and 21 PSI for acetylene.

## Description

Never connect a torch to acetylene and oxygen tanks without installing a set of flashback arrestors in the hoses at the regulators. Without these safety devices, it is possible a flash can occur within the hose, and ultimately follow back into the tanks, causing an explosion. This would be an extremely rare occurrence, but flashback arrestors will make it a "never" occurrence. Check valves are only a first line of defense and may not ultimately stop a flashback. Only the flashback arrestors will.

## Features

- Application: For installation between the regulator and hoses
- Specification: Standard “B” Fittings (9/16"- 18 UNF) fits most twin hoses
- Note: The acetylene arrestor in this set can also be used for Propane or Mapp gas
- Check Valve: The one-way valve design allows the flashback arrestor to guarantee that gas can merely flow in one direction instead of back flow to prevent accidents
- Brass Material: The flashback arrestor is formed by pure copper, which is sturdy and durability. The maximum bearing pressure of oxygen check valve is 20bar/290PSI. The maximum bearing pressure of acetylene check valve is 1.5bar/21PSI
