All components that come into contact with oxygen (including connectors, Bourdon tubes, mechanisms, etc.) must undergo rigorous degreasing and cleaning before assembly to ensure no grease residue remains. The assembly workshop must also be an oil-free environment.
Avoid using materials that easily generate sparks upon impact or friction (such as certain aluminum materials). Connector threads are typically made of copper alloys that do not easily generate sparks.
Measuring systems (such as Bourdon tubes) are typically made of copper alloys (such as phosphor bronze, brass) or stainless steel. These materials are not only resistant to oxygen pressure but also offer high safety and good corrosion resistance.
Oxygen reacts violently with oil or grease under high pressure, which can cause ignition or even explosion. All components in contact with oxygen must be thoroughly degreased and assembled in an oil-free environment to ensure safe operation.
The Bourdon tube is made of brass or other copper alloys such as phosphor bronze. These materials offer excellent resistance to oxygen pressure, high safety standards, and good corrosion resistance, making them ideal for oxygen service applications.
Spark-proof construction means that materials prone to generating sparks upon impact or friction are avoided. Connector threads are made from copper alloys that do not easily spark, reducing the risk of ignition in oxygen-rich environments.
This oxygen pressure gauge uses a 1/4" NPT thread with a lower connection location, which is a standard configuration widely compatible with industrial oxygen supply systems and equipment.
Yes. This gauge is specifically designed for applications requiring safe and reliable oxygen pressure monitoring, including hospital central oxygen supply systems, oxygen cylinders, manifolds, and oxygen generators.
Absolutely. This gauge is well-suited for metal processing and welding environments, including oxygen cutting and oxyacetylene welding equipment, thanks to its spark-proof design and oil-free construction that meet the strict safety requirements of these applications.
