Product Specification

2" 50mm OXYGEN Pressure Gauge | 0-4000 PSI | Natural & LPG Gas Compatible

Product Overview: 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, from the 316 stainless steel Bourdon tube to specialized seals, undergoes rigorous oxygen-compatible cleaning and assembly to prevent combustion—a critical feature not found in standard gauges.

• High-Pressure Capability: With a 0-4000 PSI range, this gauge is engineered for high-pressure oxygen cylinders, medical gas systems, industrial oxygen lines, and high-pressure natural gas or LPG applications.

• Versatile Gas Compatibility: Beyond oxygen, its contaminant-free construction and compatible materials make it an ideal choice as a precision natural gas pressure gauge and LPG gas pressure gauge for testing, distribution, and process control.

• Compact & Precise: The 2-inch (50mm) size provides excellent portability for field service and test kits while maintaining the accuracy needed for critical gas measurement as a reliable gas pressure manometer.

• Safety-First Design: Features include a solid front safety case, dedicated "OXYGEN USE ONLY" markings (when configured for oxygen), and a bleeder valve option to ensure 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:

• Oxygen-Specific Cleaning: All parts are degreased and assembled in a controlled environment.

• Material Selection: Only non-combustible, oxygen-compatible metals and elastomers are used.

• Dedicated Use Marking: Clearly identified to prevent cross-contamination with other gas systems.

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: As a high-pressure natural gas pressure gauge for wellhead testing, compressor stations, and distribution.

• LPG & Fuel Gases: As a LPG gas pressure gauge for bulk storage, transfer, and vehicle fuel system testing.

• Laboratory & Research: High-purity gas systems and experimental setups requiring a precise gas pressure manometer.

Ordering & Safety Compliance

electing the correct gauge for gas service is a safety-critical decision. We provide guidance on thread types (CGA, NPT), certifications, and proper application.
