Global Industrial B2781372 Compressed Gas Gauge 3000 Psi

Product Description

The GLOBAL INDUSTRIAL B2781372 is a 2-inch Bourdon tube compressed gas gauge rated to 3000 PSI with a 1/4-inch NPT lower mount connection and a polished brass case. The Bourdon tube is engineered with low copper content, making it safe for acetylene service on pressure ranges at or below 800 PSI. Wetted parts are constructed from a brass copper alloy. The white aluminum dial provides clear readability, and the removable twist-off polycarbonate window simplifies dial servicing without full gauge removal. Cleaned to ASME B40.100 Level IV and UL approved, this gauge meets recognized industry standards for compressed gas applications.

This gauge is suited for compressed gas systems in industrial, welding, and mechanical service environments. The lower mount configuration fits standard manifolds, regulators, and panel installations where a bottom-entry connection is required. The polished brass case resists corrosion in typical shop and field conditions. The ambient operating temperature range of -40 to 140 degrees F covers most indoor and outdoor service scenarios. Installation is typically performed by pipefitters, welding technicians, or industrial mechanics working on compressed gas distribution or regulator assemblies.

Installation Notes

Compressed gas gauge installation should be performed by a qualified pipefitter or gas system technician. Always depressurize and isolate the gas line before removing or installing any gauge. Apply thread sealant rated for compressed gas service to the NPT threads - do not use PTFE tape on acetylene service connections unless the tape is rated for that application. Follow all applicable OSHA, CGA, and local compressed gas handling codes during installation and service.
