Global Industrial B2781335 Compressed Gas Gauge 200 Psi

Product Description

The GLOBAL INDUSTRIAL B2781335 is a 2-inch compressed gas pressure gauge rated to 200 PSI with a 1/4-inch NPT lower mount connection. It is built around a Bourdon tube with low copper content, making it safe for use with acetylene and other gases where copper content must be controlled. The wetted parts are constructed from a brass copper alloy, and the polished brass case is designed for long-lasting durability in demanding shop and field environments. The gauge reads from 0 to 200 PSI and is cleaned to ASME B40.100 Level IV. It is installed and serviced by HVAC technicians, welding professionals, and industrial maintenance trades.

This gauge is suited for compressed gas applications including welding, cutting, and general industrial gas distribution systems. The lower mount connection allows straightforward inline or manifold installation. The removable twist-off polycarbonate window makes dial cleaning and service accessible without specialized tools. The white aluminum dial provides clear readability under typical shop lighting conditions. Ambient operating temperature range is -40 degrees F to 140 degrees F, covering most indoor and outdoor service environments.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed gas system safety procedures. Shut off and bleed down the gas supply line completely before removing or installing any pressure gauge. Apply thread sealant rated for gas service to the NPT threads and avoid overtightening, which can crack the gauge body or distort the connection. Verify that the gauge pressure range and wetted materials are compatible with the specific gas being used before placing the system back in service.
