Esab 999446 Pressure Gauge 4000 Psi 2.5 Inch Green

Product Description

The ESAB 999446 is a pressure gauge designed for use with gas regulation equipment in welding and cutting applications. The gauge features a 2.5-inch diameter dial face in green, indicating its calibration for oxygen service, and is rated to a maximum outlet pressure of 4000 psi. It is a direct-reading instrument used to monitor downstream line pressure on regulators, ensuring accurate gas flow control during welding, cutting, or heating operations. HVAC technicians, welders, and gas system service professionals install this gauge as a replacement component on regulator assemblies.

This gauge is suited for high-pressure gas service environments including welding shops, fabrication facilities, and industrial job sites. The green color coding follows standard industry convention for oxygen cylinder and regulator equipment. It installs on compatible regulator bodies as a replacement gauge when an existing unit becomes damaged, reads inaccurately, or fails inspection. Its 2.5-inch face provides clear pressure readability during active gas flow operations.

Key Features

• 4000 psi maximum outlet pressure rating for high-pressure gas service
• 2.5-inch diameter dial for clear, at-a-glance pressure readings
• Green color coding consistent with oxygen service industry standards
• Compact form factor at 6.9 inches width and 4.3 inches height overall packaging dimensions
• Sold individually as a direct replacement unit

Compatibility

Designed as an OEM-style replacement pressure gauge for compatible ESAB gas regulators rated for high-pressure service. Verify thread type and gauge port size on the existing regulator body before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure gas systems and applicable codes. Shut off the cylinder valve and bleed all downstream pressure before removing the existing gauge. Use appropriate thread sealant rated for oxygen service — never use standard pipe dope or petroleum-based compounds on oxygen equipment. Inspect the gauge port threads on the regulator body for damage before installing the replacement gauge.
