The black iron shell oxygen gauge, also known as the black iron shell oxygen pressure gauge or oil-free oxygen gauge, is an essential oil-free pressure measuring instrument specifically designed for oxygen media. This product features a robust black iron powder-coated shell combined with an oil-free pressure measuring system, making it ideal for various applications such as oxygen cylinders, welding and cutting operations, medical oxygen supply, and chemical processing. It serves the critical purpose of oxygen pressure display and safety monitoring. With its low cost, excellent protection, and strong adaptability, this gauge is a reliable choice for many industries.

Constructed from corrosion-resistant and impact-resistant black iron, the gauge is equipped with a durable glass crystal suitable for both industrial and outdoor environments. The pressure sensing elements consist of phosphor bronze or copper alloy Bourdon tubes, while the movement and connectors are made entirely from copper alloy. The oil-free design eliminates the risk of explosion caused by the mixture of grease and oxygen, ensuring safety in all applications.

The indication and scale unit includes a clearly marked pointer and dial for easy reading of pressure units (MPa/PSI), with dual scale options available for intuitive pressure value display. The connection and sealing components feature robust copper connectors, with thread options in NPT, BSP, ZG, and more, complemented by sealing gaskets for airtight and leak-proof operation. As a trusted China supplier and factory, we ensure top-quality manufacturing and performance in every black iron shell oxygen gauge.
