1. Introduction
Thank you for choosing the TUXING 4500Psi PCP Filling Regulator Valve Air Hose. This product is designed for safely filling high-pressure air cylinders, SCBA cylinders, SCUBA diving steel cylinders, or PCP tanks. This manual provides essential information for the correct assembly, operation, and maintenance of your filling station. Please read these instructions thoroughly before use to ensure safe and efficient operation.
2. Safety Information
WARNING: High-pressure air can be extremely dangerous. Failure to follow these safety instructions may result in serious injury or death.
- Always wear appropriate personal protective equipment, including eye protection, when handling high-pressure equipment.
- Ensure all connections are clean, free of debris, and securely tightened before pressurizing the system.
- Never exceed the maximum working pressure of any component in your system (tank, hose, or regulator). The maximum operating pressure for this regulator is 450 Bars (6000 psi).
- Do not use oil or grease on any part of the regulator or hose, especially near oxygen or high-pressure air, as this can cause an explosion. The gauge is marked "USE NO OIL".
- Always open and close valves slowly to prevent sudden pressure surges.
- Depressurize the system completely using the release valve before disconnecting any components.
- Inspect the hose and regulator for any signs of damage, wear, or leaks before each use. Do not use if damaged.
- Keep out of reach of children.

5. Setup Instructions
Follow these steps to properly set up your TUXING PCP Filling Regulator Valve Air Hose:
- Inspect Components: Before assembly, visually inspect all components for any damage, wear, or foreign objects. Ensure all O-rings are in place and undamaged.
- Connect Regulator to Tank: Screw the M18x1.5 threaded end of the regulator valve onto the valve of your high-pressure air cylinder (HPA, SCBA, SCUBA, or PCP tank). Ensure the threads match and tighten securely by hand, then use an appropriate wrench on the designated wrench position for a firm, leak-free connection. Do not overtighten.
- Connect High-Pressure Hose: Attach the 8mm male quick disconnect fitting of the high-pressure hose to the corresponding female quick disconnect port on the regulator. Ensure it clicks into place securely.
- Connect to Device: Connect the 8mm female quick plug on the other end of the hose to the fill port of your PCP airgun or other device.
- Verify Connections: Double-check all connections for tightness and proper seating.

6. Operating Instructions
Once the filling station is properly set up, follow these steps to fill your PCP device:
- Close Valves: Ensure both the On/Off Valve and the Release Valve on the regulator are fully closed (turned clockwise).
- Open Tank Valve: Slowly open the valve on your main high-pressure air cylinder. The pressure gauge on the TUXING regulator will show the pressure from the main tank.
- Open On/Off Valve: Slowly turn the On/Off Valve (larger knob) counter-clockwise to allow air to flow from the main tank into the hose and your PCP device. Monitor the pressure gauge on your PCP device (if applicable) or the TUXING regulator's gauge to reach the desired fill pressure.
- Close On/Off Valve: Once the desired pressure is reached, close the On/Off Valve (turn clockwise).
- Close Tank Valve: Close the valve on your main high-pressure air cylinder.
- Release Residual Pressure: Slowly open the Release Valve (smaller knob) counter-clockwise to vent any residual pressure from the hose. You will hear air escaping. Wait until the pressure gauge reads zero.
- Disconnect: Once all pressure is released, you can safely disconnect the hose from your PCP device and then from the regulator.

7. Maintenance
Proper maintenance ensures the longevity and safe operation of your filling station:
- Cleaning: Wipe down the regulator and hose with a clean, dry cloth after each use. Do not use harsh chemicals or solvents.
- Inspection: Regularly inspect the hose for kinks, cuts, or abrasions. Check all fittings for signs of wear or damage.
- O-Rings: Periodically inspect O-rings for cracks or flattening. Replace them if necessary. Use only compatible O-rings and ensure they are clean before installation.
- Storage: Store the filling station in a clean, dry place, away from direct sunlight and extreme temperatures. Ensure it is depressurized before storage.
8. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Air Leak at Connections | Loose connection, damaged O-ring, debris in threads. | Ensure connections are tight. Inspect and replace O-rings if damaged. Clean threads. |
| Gauge Not Reading Pressure | Tank valve not open, On/Off valve closed, faulty gauge. | Ensure tank valve is open. Open On/Off valve. If problem persists, contact support. |
| Cannot Fill Device | Device fill port blocked, insufficient pressure in main tank, valves not fully open. | Check device fill port. Verify main tank pressure. Ensure both tank and On/Off valves are open. |
| Air Escaping from Release Valve during Fill | Release valve not fully closed. | Ensure Release Valve is fully closed before opening the On/Off Valve. |
