Introduction
This manual provides instructions for the proper installation, operation, and maintenance of your LDEXIN 0-180PSI Utility Air Pressure Gauge. Please read this manual thoroughly before use to ensure safe and efficient operation. This gauge is designed for measuring pressure in various systems, including air compressors, water, oil, and gas lines.
Safety Information
- Always ensure the pressure gauge is compatible with the system's pressure range. Do not exceed the maximum rated pressure of 180 PSI (12 kg/cm²).
- Wear appropriate personal protective equipment (PPE), such as safety glasses, when installing or removing the gauge.
- Ensure proper sealing using thread sealant (e.g., PTFE tape) to prevent leaks during operation.
- Do not attempt to repair a damaged gauge. Replace it immediately if any damage or inaccuracy is observed.
- Relieve all system pressure before attempting to install, remove, or service the gauge.

- Pressure range: 0~180 PSI and 0~12 Kg/cm².
- Constructed with plastic and metal materials for durability.
- Black steel case with copper alloy dry internal parts and a glass face for protection.
- Easy-to-read dial with dual scale: red markings for PSI, black markings for Bar/kg/cm².
- Arabic numerals and clear scale ensure accurate readings.
- Suitable for hydraulic and pneumatic systems, compressors, regulators, and industrial machinery.
- Designed for fluid or gaseous mediums.
Product Images:

This image displays two LDEXIN air pressure gauges, highlighting their clear dials with dual scales for PSI, kg/cm², and kPa readings. The gauges feature a black needle and a red maximum pressure indicator.

This image shows the front of the pressure gauge with a measurement line indicating its 5.3cm (2.1 inch) dial plate outer diameter, crucial for fitment.

This image provides a view of the back of the pressure gauge, focusing on the threaded connection. A measurement line indicates the thread diameter is 1.1cm (0.43 inch), which corresponds to the 7/16" / 11mm thread mentioned in the product title.
Setup
- Compatibility Check: Ensure the gauge's pressure range (0-180 PSI) and thread size (7/16" / 11mm, or 1/8 BSP if applicable) are compatible with your system's requirements.
- System Preparation: Turn off the system and relieve any existing pressure before attempting installation. This prevents injury and damage.
- Installation: Carefully thread the gauge into the appropriate port on your system. Apply a suitable thread sealant, such as PTFE tape, to the gauge threads to ensure a leak-free connection. Hand-tighten first, then use a wrench for a snug fit, but do not overtighten as this can damage the threads or the gauge.
- Positioning: Orient the gauge so that the dial is easily visible and accessible for reading.
- System Activation: Slowly repressurize the system. Carefully check for any leaks around the gauge connection point. If leaks are detected, depressurize the system and re-tighten the connection or reapply thread sealant.
Operating Instructions
Once the gauge is installed and the system is pressurized, the black needle on the dial will indicate the current pressure. The gauge features a dual scale for convenience:
- Red Markings: Indicate pressure in PSI (pounds per square inch).
- Black Markings: Indicate pressure in kg/cm² (kilograms per square centimeter) and kPa (kilopascals).
Read the value corresponding to the desired unit by observing the position of the needle against the respective scale.
Maintenance
- Cleaning: Wipe the gauge face and body with a soft, damp cloth to remove dust and grime. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or the clear face.
- Inspection: Periodically inspect the gauge for any signs of physical damage, such as cracks in the casing or glass, a bent needle, or corrosion. Check the connection point for any signs of leakage or wear.
- Replacement: If any damage is observed, if the gauge provides inconsistent or inaccurate readings, or if the needle becomes stuck, the gauge should be replaced immediately to ensure system safety and accurate measurement.
- Storage: If the gauge is removed from service for storage, keep it in a clean, dry environment, protected from extreme temperatures, humidity, and physical impacts.
Troubleshooting
- No Reading or Stuck Needle:
- Ensure the system is properly pressurized and the gauge is connected to an active pressure line.
- Verify that the gauge's connection port is not obstructed.
- If the system is pressurized and the needle remains unresponsive, the gauge may be faulty and require replacement.
- Inaccurate Reading:
- Compare the reading with another known accurate gauge if available.
- Confirm that the gauge's pressure range is appropriate for the system's operating pressure.
- Physical damage or prolonged use in harsh conditions can affect accuracy. Consider replacing the gauge.
- Leaks at Connection Point:
- Depressurize the system. Re-examine the threads and ensure sufficient thread sealant (e.g., PTFE tape) was applied.
- Check for proper thread engagement and ensure the gauge is tightened appropriately. Avoid overtightening.
- Inspect both the gauge's threads and the system's port threads for any damage or burrs that could prevent a proper seal.
