3. Setup and Installation
The GRYVOZE Fuel Hose Swivel is designed for straightforward installation. Follow these steps to ensure a secure and leak-free connection.
- Prepare Components: Ensure you have the fuel hose swivel, your fuel hose, and the fuel nozzle or pump outlet. Check that all threads are clean and free of debris.
- Apply Thread Sealant: It is recommended to use a UL-listed thread sealant approved for use with the specific fuel type (e.g., gasoline, diesel) on the NPT threads of the swivel. This helps prevent leaks.
- Connect to Hose: Thread one end of the fuel hose swivel onto the fuel hose. Tighten securely using an appropriate wrench. The thickened nut design (0.5 inches) facilitates easier tightening compared to standard 0.3-inch nuts.
- Connect to Nozzle/Pump: Thread the other end of the fuel hose swivel onto the fuel nozzle or pump outlet. Tighten securely.
- Verify Connections: After installation, visually inspect all connections to ensure they are tight. Perform a leak test before full operation.

4. Operating Instructions
The GRYVOZE Fuel Hose Swivel allows for flexible and safe fuel transfer. Its dual 360° rotation feature eliminates hose twisting and kinking.
- Positioning: Once installed, the swivel allows the fuel nozzle to rotate freely in multiple planes (360°, 270°, 180°, 90°). Adjust the nozzle to the most comfortable and efficient fueling angle without needing to reposition the hose or tank.
- Preventing Kinks: The multi-plane rotation actively prevents the fuel hose from twisting, binding, or kinking, which extends the life of the hose and maintains consistent flow.
- Safe Fuel Transfer: The secure connections and smooth rotation contribute to a safer refueling process by minimizing strain on connections and reducing the chance of accidental disconnections or spills.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your GRYVOZE Fuel Hose Swivel.
- Regular Inspection: Periodically inspect the swivel for any signs of wear, damage, or corrosion. Check the connections for tightness and ensure there are no leaks.
- Cleaning: Keep the exterior of the swivel clean from dirt, grime, and fuel residues. Use a soft cloth and appropriate cleaning agents if necessary.
- Lubrication: The internal ball bearings are designed for smooth operation. If rotation becomes stiff over time, a small amount of fuel-compatible lubricant may be applied to the rotating joints, though this is generally not required for normal operation.
- Storage: When not in use for extended periods, store the swivel in a clean, dry environment to prevent exposure to harsh elements.
6. Troubleshooting
If you encounter issues with your GRYVOZE Fuel Hose Swivel, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fuel Leakage | Loose connections, insufficient thread sealant, damaged O-rings. | Tighten all connections. Reapply UL-listed thread sealant. Inspect and replace O-rings if damaged. |
| Stiff Rotation | Accumulation of dirt/debris, lack of lubrication. | Clean the rotating joints. Apply a small amount of fuel-compatible lubricant if necessary. |
| Incompatible Fit | Incorrect NPT size. | Ensure the swivel is 3/4 Inch NPT, matching your hose and nozzle. Verify thread compatibility before purchase. |
