Installation Guidelines
Proper installation is crucial for the optimal performance and longevity of the nylon tube. Follow these guidelines:
- Preparation: Ensure the tube is cut cleanly and squarely using a tube cutter. Avoid using knives or shears that can deform the tube end, which may lead to leaks.
- Fittings: Use fittings specifically designed for nylon tubing of 5/8" diameter. Ensure fittings are clean and free of debris.
- Connection: Insert the tube fully into the fitting until it bottoms out. For push-to-connect fittings, a slight tug back will confirm a secure connection. For compression fittings, tighten according to manufacturer specifications.
- Routing: Route the tubing to avoid sharp bends, kinks, or areas of high heat or abrasion. Use appropriate clamps or supports to prevent excessive movement or strain.
- Pressure Testing: After installation, slowly pressurize the system and check for any leaks at all connection points. Address any leaks immediately.
Application and Use
The Velvac 5/8" nylon tube is commonly used in various applications, including:
- Air brake systems in commercial vehicles.
- Pneumatic control lines.
- Fuel lines (check compatibility with specific fuel types).
- Lubrication systems.
- General industrial fluid transfer.
Always ensure the tube's specifications (pressure, temperature, chemical compatibility) meet the requirements of your specific application.

Maintenance and Care
To ensure the longevity and reliability of your Velvac nylon tube, consider the following maintenance practices:
- Regular Inspection: Periodically inspect the tube for signs of wear, abrasion, kinks, cracks, or discoloration. Pay close attention to areas near fittings and where the tube passes through tight spaces.
- Cleaning: Clean the exterior of the tube as needed to remove dirt, grease, or other contaminants that could degrade the material over time. Use mild soap and water; avoid harsh chemicals.
- Environmental Protection: Protect the tube from prolonged exposure to direct sunlight, extreme temperatures, or corrosive chemicals unless specifically rated for such conditions.
- Storage: If storing unused tube, keep it in a cool, dry place away from direct sunlight and sharp objects. Keep it coiled to prevent kinks.
Troubleshooting
Common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Leak at fitting | Improperly cut tube end, tube not fully inserted, damaged fitting, incorrect fitting type. | Re-cut tube end cleanly and squarely. Ensure full insertion into fitting. Replace damaged fitting. Verify fitting compatibility. |
| Tube kinked or flattened | Excessive bending radius, external pressure, improper routing. | Re-route tube to allow for larger bend radii. Protect tube from external crushing forces. Replace severely kinked sections. |
| Reduced flow/pressure | Internal blockage, severe kinking, tube collapse due to vacuum. | Inspect for blockages and clear. Check for kinks and re-route. Ensure system design prevents vacuum collapse if applicable. |
