Flashback Arrestor for Oxygen Regulator — Full Copper, Precision Polished

1. Product Overview

2. Key Features

Full Copper Body Construction

• Superior corrosion resistance — withstands oxygen service and harsh workshop environments without degradation
• Excellent thermal conductivity — dissipates heat quickly during flashback events, reducing thermal stress
• Non-sparking material — copper is inherently non-sparking, an essential safety feature for oxygen service
• Long service life — copper resists oxidation and corrosion better than brass or steel alternatives

Precision Polished Finish

• Smooth surface — reduces contamination buildup and makes cleaning easier
• Professional appearance — polished copper finish signals quality and reliability
• Oxidation resistance — polished surface resists tarnishing over time
• Easy inspection — smooth surface makes it easy to detect any damage or wear

Flashback Prevention — Critical Safety Protection

1. Reverse Gas Flow — prevents oxygen from flowing backward into the fuel gas system, which could create an explosive mixture
2. Flame Propagation — stops flame from traveling back through the hose to the regulator and gas cylinder, preventing catastrophic explosions

• Operator safety — protects welders and nearby workers from explosion injuries
• Equipment protection — prevents damage to expensive regulators, hoses, and gas cylinders
• Worksite safety — reduces the risk of fires and explosions in the welding area
• Regulatory compliance — meets occupational safety requirements for oxy-fuel operations

Compact & Lightweight Design

• Easy installation — screws directly onto the regulator outlet without special tools
• Minimal weight — does not add significant weight to the regulator or hose assembly
• Compact size — fits in tight spaces without interfering with other equipment
• Low profile — streamlined design reduces the risk of snagging or damage

Oxygen Service Rated

• Oxygen-compatible materials — all components are safe for use with high-pressure oxygen
• Clean assembly — manufactured and assembled in oxygen-clean conditions to prevent contamination
• Pressure rated — designed to withstand the working pressures of oxygen regulators
• Certified for oxygen use — meets safety standards for oxygen service applications

5. How It Works

Flashback Arrestor Operation

1. Check Valve (Non-Return Valve)
   • Allows gas to flow in only one direction (from regulator to hose)
   • Automatically closes if gas attempts to flow in reverse
   • Prevents oxygen from entering the fuel gas system
2. Flame Arrestor Element
   • Contains a sintered metal filter with precisely controlled pore size
   • Cools and extinguishes any flame attempting to pass through
   • Stops flame propagation before it reaches the regulator or cylinder

6. Applications

• Oxy-Acetylene Welding

  Essential safety device for all oxy-acetylene welding operations to prevent flashback into oxygen cylinders.

• Oxy-Acetylene Cutting

  Critical protection during cutting operations where flashback risk is elevated due to close proximity to the workpiece.

• Brazing & Soldering

  Safety protection for torch brazing and soldering operations using oxygen-fuel gas mixtures.

• Heating Applications

  Protects oxygen supply during metal heating, bending, and forming operations.

• Industrial Fabrication Shops

  Mandatory safety equipment for all oxy-fuel stations in manufacturing and fabrication facilities.

• Construction Sites

  Required safety device for field welding and cutting operations on construction projects.

• Shipbuilding & Marine Welding

  Essential protection in shipyard welding environments where flashback risk is high.

• Pipeline & Pressure Vessel Work

  Critical safety device for welding and cutting in oil & gas and chemical industries.

8. FAQ

Q1: What is a flashback arrestor and why is it important?

1. Reverse gas flow — stops oxygen from flowing backward into the fuel gas system
2. Flame propagation — stops flame from traveling back through the hose to the regulator and gas cylinder

• Cylinder explosion — flame reaching the oxygen cylinder could cause a catastrophic explosion
• Operator injury — explosions can cause severe burns, shrapnel injuries, or death
• Equipment damage — regulators, hoses, and cylinders can be destroyed

Q2: Why is copper the preferred material for oxygen service flashback arrestors?

• Non-sparking — copper does not create sparks when struck or rubbed, eliminating ignition risk in oxygen-rich environments
• Corrosion resistant — copper resists oxidation and corrosion in oxygen service, ensuring long-term reliability
• Thermally conductive — copper dissipates heat quickly during flashback events, reducing thermal stress on the device
• Oxygen-compatible — copper is chemically compatible with high-pressure oxygen and does not react dangerously

• Brass contains zinc, which can spark under certain conditions
• Aluminum can ignite in high-pressure oxygen environments

Q3: Where should the flashback arrestor be installed?

1. Ensure the oxygen cylinder valve is closed
2. Remove the oxygen hose from the regulator outlet
3. Screw the flashback arrestor onto the regulator outlet thread (hand-tight, then wrench-tight)
4. Reconnect the oxygen hose to the flashback arrestor outlet
5. Check all connections for leaks using soapy water

Q4: Can I use this flashback arrestor for fuel gas (acetylene/propane)?

Q5: How often should I replace the flashback arrestor?

• Visual inspection — check for damage, corrosion, or leaks before each use
• Annual testing — professional testing and certification annually (required in many jurisdictions)
• Replacement — replace every 1-2 years, or immediately after any flashback event
• After flashback — if a flashback occurs, the arrestor must be replaced even if it appears undamaged

Q6: Does this flashback arrestor affect gas flow or pressure?

• Flow resistance — our arrestor is designed with low flow resistance to ensure adequate gas supply to the torch
• Pressure drop — minimal pressure drop across the device (typically <0.1 bar at normal flow rates)
• No adjustment needed — once installed, no pressure adjustments are required

• Improper installation (cross-threaded or not fully tightened)
• Contamination or blockage in the arrestor
• Incompatible thread size

Q7: Is the flashback arrestor reusable after a flashback event?

1. Replace the flashback arrestor immediately
2. Inspect the entire gas system (hoses, regulator, torch) for damage
3. Identify and correct the cause of the flashback before resuming work
4. Consider additional training on safe oxy-fuel practice

Q8: Can I get a sample before placing a bulk order?

Q9: What certifications does this flashback arrestor have?

• EN 730 — Gas welding equipment — Flashback arrestors for fuel gases and oxygen
• ISO 5175 — Gas welding equipment — Non-return valves for fuel gases and oxygen
• CE Certification — European conformity for personal protective equipment and gas equipment
