1pcs Bar Air Pressure Gauge 13mm 1/4 BSP Thread | Dual Scale for Air Compressor

This bar air pressure gauge offers a clear dual-scale readout in both PSI and Bar, making it a practical tool for monitoring your air compressor. With a compact 40mm dial and a standard 1/4 BSP thread, it is simple to install and easy to read at a glance.

The gauge is built with a durable iron shell and features a double scale that measures from 0 to 180 PSI and 0 to 12 Bar. This allows you to quickly check pressure levels without needing to convert units, saving time during your work. Its small size means it fits well in tight spaces on compressors, regulators, or air tools.

Whether you are inflating tires, powering pneumatic tools, or checking line pressure, this gauge gives you reliable readings. The black face and white markings offer good contrast for visibility in various lighting conditions. It is a straightforward, no-fuss accessory for anyone who needs accurate pressure monitoring.

Usage Scenario

Mark was setting up his new air compressor in the garage and needed a reliable way to monitor output pressure. He installed this compact gauge directly on the regulator using the 1/4 BSP thread. The dual scale let him see both PSI and Bar without any mental math. Now he can quickly adjust the pressure for his nail gun or tire inflator, knowing exactly what he is working with.

Micro Comparison

Unlike digital gauges that require batteries and can be harder to read in bright sunlight, this analog gauge offers instant, no-power readings. Its dual scale is more convenient than single-unit gauges because you avoid conversion errors. The compact 40mm size also makes it easier to fit in tight spots compared to larger workshop gauges.
