Uniweld g1d 400 Psi 2 Inch Brass Welding Pressure Gauge

Product Description

The UNIWELD g1d is a 2-inch, 400 PSI stem-mount pressure gauge built for use with compressed gas regulators in welding and medical gas applications. The gauge is oxygen cleaned to ANSI B40.1 standards, making it suitable for oxygen service, other fuel gases, and non-corrosive medical gas equipment. Construction features a brass and steel case with a one-piece polycarbonate lens. Licensed HVAC and refrigeration technicians, welders, and industrial gas service professionals install this gauge as a direct replacement on regulators requiring a 2-inch dial format.

The g1d is designed for stem-mounting applications where a compact gauge profile is required. Typical use cases include replacement of worn or damaged gauges on compressed gas regulators used in welding shops, medical facilities, and industrial gas handling environments. Its compatibility with oxygen, fuel gases, and non-corrosive medical gases makes it a versatile replacement option across multiple service disciplines.

Key Features

• Oxygen cleaned to ANSI B40.1 standards for safe use in oxygen and fuel gas service
• 400 PSI pressure range suitable for compressed gas regulator applications
• Brass and steel case construction for durability in shop and field environments
• One-piece polycarbonate lens for impact resistance and clear dial visibility
• Stem-mount design for direct regulator installation
• Suitable for non-corrosive medical gas equipment use

Compatibility

Designed as an OEM-style replacement gauge for stem-mount compressed gas regulators used in welding, fuel gas, and non-corrosive medical gas applications.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed gas systems and applicable safety codes. Always depressurize and isolate the regulator completely before removing or installing a gauge. Use appropriate thread sealant rated for oxygen service where required, and verify the connection is leak-free before returning the system to service. Never over-torque the gauge stem fitting, as this can damage the brass threads.
