1. Introduction
This manual provides essential instructions for the safe and effective installation, operation, and maintenance of the Enerpac G2514L Hydraulic Pressure Gauge. Please read this manual thoroughly before using the product.
The Enerpac G2514L is a 2-1/2 inch diameter face pressure gauge designed for hydraulic systems, featuring a dual scale for readings from 0 to 1,000 PSI and 0 to 70 Bar. It includes a lower-mount connection with 1/4 inch NPTF male threads and is glycerin-filled for stable readings and enhanced visibility.
2. Safety Information
- Always ensure the hydraulic system is depressurized before installing or removing the gauge.
- Do not exceed the maximum rated pressure of 1,000 PSI (70 Bar). Over-pressurization can damage the gauge and lead to system failure.
- Wear appropriate personal protective equipment (PPE) when working with hydraulic systems.
- Inspect the gauge for any visible damage before each use. Do not use a damaged gauge.
- Ensure proper thread sealant is used during installation to prevent leaks.
- The gauge contains glycerin. In case of rupture, avoid contact with skin and eyes. Refer to safety data sheets if necessary.
3. Components Overview
The Enerpac G2514L Hydraulic Pressure Gauge consists of the following primary components:
- Gauge Face: 2-1/2 inch diameter, displaying dual scales for PSI and Bar.
- Pointer: Indicates the current pressure reading.
- Glycerin Filling: Internal fluid for dampening pulsations and lubricating internal components, improving readability and longevity.
- Lower-Mount Connection: 1/4 inch NPTF male threads for connection to the hydraulic system.
- Safety Blow-out Disk: Designed to release pressure safely in case of internal over-pressurization.

4. Setup and Installation
- Depressurize System: Ensure the hydraulic system is completely depressurized and isolated before beginning installation.
- Prepare Connection Point: Clean the female NPTF port where the gauge will be installed, ensuring it is free from debris.
- Apply Sealant: Apply an appropriate thread sealant (e.g., PTFE tape or liquid sealant) to the 1/4 inch NPTF male threads of the gauge.
- Install Gauge: Carefully thread the gauge into the system's port. Hand-tighten first, then use a wrench to tighten until snug. Do not overtighten, as this can damage the threads or the gauge. Ensure the gauge face is oriented for easy reading.
- Inspect for Leaks: Once installed, slowly re-pressurize the hydraulic system and check for any leaks around the connection point.
5. Operation
The Enerpac G2514L gauge provides direct pressure readings:
- Reading Pressure: The black pointer indicates the current pressure. The outer scale (black markings) displays pressure in PSI (pounds per square inch), ranging from 0 to 1,000 PSI. The inner scale (red markings) displays pressure in Bar, ranging from 0 to 70 Bar.
- Glycerin Filling: The glycerin filling helps to dampen pointer fluctuations caused by system pulsations, providing a more stable and accurate reading. It also lubricates internal components, extending the gauge's lifespan.
- Accuracy: The gauge has an accuracy rating of +/-1.5% of full scale.
6. Maintenance
- Regular Inspection: Periodically inspect the gauge for any signs of damage, such as a cracked face, bent pointer, or leaks around the connection.
- Cleaning: Clean the gauge face with a soft, damp cloth. Do not use harsh chemicals or abrasive materials that could scratch the face or damage the casing.
- Calibration: For critical applications, periodic calibration by a qualified technician is recommended to ensure continued accuracy.
- Storage: If removing the gauge from service, store it in a clean, dry environment, protected from extreme temperatures and physical impact.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No pressure reading / Pointer stuck at zero | System not pressurized; Gauge port blocked; Internal damage. | Verify system pressure; Check for obstructions in the port; Replace gauge if damaged. |
| Inaccurate readings | Gauge out of calibration; Damage to internal mechanism; Extreme temperature fluctuations. | Calibrate or replace gauge; Ensure operating within specified temperature range. |
| Glycerin leakage | Seal failure; Casing damage; Over-pressurization leading to safety disk activation. | Replace gauge. |
| Excessive pointer vibration | System pulsations too severe for glycerin dampening; Low glycerin level. | Consider adding a snubber to the system; Replace gauge if glycerin level is low. |
