Product Description
2" 50mm OXYGEN Pressure Gauge | 0-4000 PSI | Natural & LPG Gas Compatible
Certified Safety for Critical Gas Systems
Our 2-inch (50mm) Oxygen Pressure Gauge represents the highest standard in gas measurement safety and precision. Rated for 0-4000 PSI service, this specialized instrument is manufactured, cleaned, and certified for oxygen compatibility, eliminating ignition risks. While designed for oxygen, its robust construction and material specifications make it equally suitable as a high-integrity natural gas pressure gauge and LPG gas pressure gauge for industrial and laboratory applications where purity and safety are paramount.
Key Features & Benefits
- Oxygen-Safe Certified Construction: Every component undergoes rigorous oxygen-compatible cleaning and assembly to prevent combustion
- High-Pressure Capability: 0-4000 PSI range engineered for high-pressure oxygen cylinders and gas systems
- Versatile Gas Compatibility: Suitable for oxygen, natural gas, and LPG applications with contaminant-free construction
- Compact & Precise: 2-inch size provides portability while maintaining accuracy as a reliable gas pressure manometer
- Safety-First Design: Solid front safety case, dedicated markings, and bleeder valve option for safe depressurization

Critical Safety Distinction: Oxygen vs. General Gas Gauges
A standard gauge used in oxygen service can become a severe fire hazard due to oil residue or incompatible materials. Our oxygen pressure gauge is fundamentally different with oxygen-specific cleaning, non-combustible material selection, and dedicated use marking to prevent cross-contamination. This same level of cleanliness and material integrity makes it exceptionally reliable as a natural gas pressure gauge and LPG gas pressure gauge, where purity and leak prevention are also critical.
Typical Applications
- Medical & Healthcare: Medical oxygen cylinders, hospital gas pipelines, dental air systems
- Industrial Gas: Oxygen, nitrogen, argon cylinders and distribution lines; welding gas supplies
- Energy & Utilities: High-pressure natural gas gauge for wellhead testing, compressor stations, and distribution
- LPG & Fuel Gases: LPG pressure gauge for bulk storage, transfer, and vehicle fuel system testing
- Laboratory & Research: High-purity gas systems and experimental setups requiring precise gas pressure measurement
Ordering & Safety Compliance
Selecting the correct gauge for gas service is a safety-critical decision. We provide guidance on thread types (CGA, NPT), certifications, and proper application.
