Acetylene Flashback Arrestor All Copper Fine Polished for Welding Torch

Industrial-grade all-copper acetylene flashback arrestor for welding torch, overall fine polished finish, reliable flame blocking, prevents reverse flame in gas welding cutting, 0.12kg lightweight, standard thread interface.

Product Description

Shangbang acetylene flashback arrestor for torch is made of full copper with overall fine polishing treatment. Specially designed for welding and cutting torches, it is installed at the acetylene gas inlet end of the torch to prevent flashback during operation. It effectively stops reverse flame from traveling back through the gas hose to the acetylene cylinder, protecting operators and equipment — an essential end-of-line safety device for acetylene welding and cutting systems.

Product Features

English Feature

FAQ

Q1: What’s the difference between acetylene and oxygen torch flashback arrestors? Can they be used interchangeably?
A1: They may look similar, but the internal flame arrester elements are optimized for different gas characteristics. NEVER use them interchangeably. The acetylene model (W62361) is designed for acetylene’s flammable and explosive properties, while the oxygen model (W62360) is designed for oxygen’s combustion-supporting properties. Mixing them may reduce flame blocking effectiveness and pose safety risks. Always select the correct model for your gas type.
Q2: Do I need to install both torch-side and regulator-side acetylene flashback arrestors?
A2: For optimal safety protection, installing both is recommended. The regulator-side arrestor protects the gas cylinder at the source end, while the torch-side arrestor protects the operator and torch at the working end. Using both together provides dual protection with a higher safety factor than installing just one.
Q3: How to choose between all-copper and zinc alloy flashback arrestors?
A3: For safety and durability, all-copper material is the priority choice. All-copper offers better corrosion resistance, high-temperature resistance and air tightness, with a service life several times that of zinc alloy — not prone to aging or gas leakage with long-term use. Zinc alloy is cheaper but has poor stability in high-temperature environments, posing safety risks. Since acetylene is a flammable and explosive gas, industrial-grade all-copper quality is recommended for safety protection products.
Q4: Is there a specific installation direction for this flashback arrestor?
A4: Yes, there is. When installing, please pay attention to the gas flow direction arrow marking on the product. The arrow should point toward the torch direction (i.e., the direction gas flows from the cylinder to the torch). Reversed installation will affect gas flow and flashback blocking effectiveness, posing safety risks. Please install correctly according to the product manual or arrow marking.
Q5: How often should a flashback arrestor be replaced?
A5: Under normal use with no flashback incidents, all-copper flashback arrestors have a long service life. Regular inspection of sealing and flame blocking performance every 6-12 months is recommended. If a flashback has occurred, gas leakage is found, appearance is damaged, or the arrester element is contaminated or aged, replace immediately. Proper use and regular maintenance can effectively extend product life.
