Uniweld tgb230 Gas Test Gauge 30 Psi 1/2 Inch Fpt

Product Description

The UNIWELD tgb230 is a gas test gauge used to measure and verify gas line pressure during installation, commissioning, and leak testing of natural gas and propane systems. The gauge features a 2 inch diameter dial with 1/4 pound increments across a 0 to 30 psi range, giving technicians a clear, precise readout without the need for digital equipment. It connects via a 1/2 inch FPT fitting, making it compatible with standard test ports found on gas train components and meter outlets. Licensed plumbers, gas fitters, and HVAC technicians are the primary users of this gauge in the field.

The tgb230 is suited for low-pressure gas system testing in residential and light commercial applications. Typical use cases include post-installation pressure checks on gas piping, appliance commissioning, and troubleshooting pressure drop issues in distribution lines. The 1/4 pound increment graduation provides the resolution needed to identify pressure loss that would otherwise go undetected on a coarser gauge.

Key Features

• 2 inch diameter dial for clear at-a-glance pressure reading
• 0 to 30 psi range covers standard low-pressure gas system test requirements
• 1/4 pound increment graduations for precise pressure loss detection
• 1/2 inch FPT connection fits standard gas test ports and tee fittings
• Compact form factor suited for field service toolkits

Compatibility

Designed for use with natural gas and propane piping systems requiring low-pressure testing up to 30 psi via a 1/2 inch FPT test connection.

Installation Notes

Gas test gauges must be installed by a licensed plumber or gas fitter in accordance with local codes and IFGC requirements. Always shut off the gas supply and depressurize the line before connecting or removing the gauge from any test port. Verify that the gauge range is appropriate for the system pressure being tested before use. Do not exceed the rated 30 psi maximum pressure on this gauge.
