,

Introducing our semi-stainless steel bottom oxygen pressure gauge, a precision instrument crafted in China by trusted suppliers and renowned factory standards. This specialized gauge is engineered for accurately measuring and indicating oxygen pressure, catering to both safety and performance.

,

Oxygen, known for its strong oxidizing properties, can lead to combustion when in contact with oils, greases, or organic materials under pressure. This makes our oxygen pressure gauge distinct from conventional pressure gauges, as it complies with rigorous oil-free safety regulations essential for handling oxygen safely.

,

The dial features a prominent red No Oil symbol or oxygen icon (like O₂) and a standard sky blue color marking, clearly differentiating it from pressure gauges intended for other media. This thoughtful design ensures safe usage and prevents any potential misuse, making it an essential tool for various applications in industries that prioritize safety and reliability.

Core Features and Advantages
🛢️
Absolutely No Oil
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.
⚡
Spark-Proof Construction
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.
🔩
Special Materials
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.
Typical Application Fields
  • 🎯 Specifically designed for industrial applications requiring safe and reliable oxygen pressure monitoring.
  • 🏥 Medical & Industrial Oxygen Supply Systems: Hospital central oxygen supply systems, oxygen cylinders/manifolds, oxygen generators.
  • 🔥 Metal Processing & Welding: Oxygen cutting, oxyacetylene welding equipment.
  • ⚗️ Chemical & Air Separation Industries: Air separation equipment, oxygen storage tanks, pipelines.
  • 🚀 Aerospace: Ground-based oxygen supply equipment testing.
  • 💧 Water Treatment: Ozone generators (ozone is produced from oxygen).
Frequently Asked Questions
Q Why must an oxygen pressure gauge be completely free of oil and grease?
Oxygen reacts violently with oil and grease under high pressure, which can cause combustion or even explosion. All components in contact with oxygen must be rigorously degreased before assembly, and the entire assembly process must take place in an oil-free environment to ensure safe operation.
Q What materials are used in the Bourdon tube and why?
The Bourdon tube is made of brass or other copper alloys such as phosphor bronze. These materials provide excellent resistance to oxygen pressure, high safety standards, and strong corrosion resistance, making them ideal for oxygen service applications.
Q What does "spark-proof construction" mean in this gauge?
Spark-proof construction means the gauge avoids materials that can generate sparks through impact or friction. The connector threads are made from copper alloys, which are inherently non-sparking, reducing the risk of ignition in oxygen-rich environments.
Q What is the thread standard and connection location for this gauge?
This oxygen pressure gauge uses a 1/4" NPT thread standard with a lower connection location, which is the most common configuration for panel-mounted or inline pressure gauge installations in industrial systems.
Q Is this gauge suitable for use in medical oxygen supply systems?
Yes. This gauge is specifically designed for safe and reliable oxygen pressure monitoring, making it fully suitable for medical applications including hospital central oxygen supply systems, oxygen cylinders, manifolds, and oxygen generators.
Q Can this gauge be used in welding and metal cutting applications?
Absolutely. This gauge is widely used in metal processing and welding applications, including oxygen cutting and oxyacetylene welding equipment, where accurate and safe oxygen pressure monitoring is critical for operational safety and efficiency.
