1. Introduction
This manual provides essential information for the safe and effective use of the USASEALING ZUSA-HT-4018 High Temperature Silicone Tubing. Please read these instructions carefully before installation, operation, or maintenance to ensure optimal performance and longevity of the product.
The ZUSA-HT-4018 tubing is designed for demanding applications requiring high purity and resistance to elevated temperatures and pressures.
2. Safety Information
- Pressure Limits: Do not exceed the maximum operating pressure of 220 psi (15.17 bar). Exceeding this limit can lead to tubing failure and potential injury.
- Temperature Limits: Ensure the operating temperature remains within the specified range for high-temperature silicone. Extreme temperatures outside this range can degrade the material.
- Chemical Compatibility: Verify chemical compatibility with the fluid being conveyed. While silicone is broadly resistant, certain chemicals can cause degradation.
- Installation: Always ensure connections are secure and leak-free. Improper installation can lead to system failure.
- Inspection: Regularly inspect the tubing for signs of wear, damage, or kinking. Replace damaged tubing immediately.
3. Product Overview
The USASEALING ZUSA-HT-4018 is a high-purity silicone tubing, platinum cured, and reinforced with a polyester braid. It is manufactured from FDA compliant materials and certified to 3A standards, making it suitable for food, beverage, dairy, and pharmaceutical applications.

Key Features:
- Material: Silicone, Reinforcement: Polyester Braid
- Grade: Food Grade, FDA compliant, 3A certified
- Hardness: Soft (60A - 80A)
- Curing Method: Platinum Cured
- Maximum Operating Pressure: 220 psi
4. Setup and Installation
- Preparation: Before installation, ensure the tubing and all connecting components are clean and free from debris.
- Cutting: Cut the tubing to the desired length using a sharp, clean tool to ensure a straight, burr-free cut.
- Connections: Securely attach the tubing to appropriate fittings. For pressure applications, use clamps or crimps designed for the tubing's outer diameter to prevent leaks.
- Routing: Route the tubing to avoid sharp bends or kinks. The minimum bend radius for this tubing is 100mm. Bending below this radius can restrict flow or damage the tubing.
- Support: Provide adequate support for long runs of tubing to prevent sagging, especially when conveying liquids.
- Pressure Testing: After installation, perform a low-pressure test to check for leaks before operating at full system pressure.
5. Operating Instructions
Operate the USASEALING ZUSA-HT-4018 tubing within its specified parameters to ensure safety and performance.
- Pressure Management: Do not exceed the maximum operating pressure of 220 psi. Monitor system pressure regularly.
- Temperature Control: Maintain fluid and ambient temperatures within the tubing's rated temperature range.
- Flow Rate: Ensure the flow rate is appropriate for the tubing's inner diameter and application to prevent excessive pressure drop or turbulence.
- Fluid Compatibility: Confirm that the fluid being transported is compatible with silicone to prevent material degradation.
6. Maintenance
- Regular Inspection: Periodically inspect the tubing for any signs of wear, cuts, abrasions, discoloration, hardening, or softening. Pay close attention to connection points.
- Cleaning: Clean the tubing as required by your application's standards. For food and pharmaceutical applications, follow strict sanitization protocols. Silicone tubing can typically be sterilized by autoclaving.
- Storage: Store unused tubing in a cool, dry place away from direct sunlight, ozone, and harsh chemicals. Keep it in its original packaging if possible to protect it from environmental factors.
- Replacement: Replace tubing at the first sign of damage or degradation to prevent system failure and contamination.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leaks at connections | Loose clamps, incorrect fitting size, damaged tubing end | Tighten clamps, verify fitting compatibility, re-cut and re-install tubing |
| Reduced flow | Kinked tubing, internal blockage, collapsed tubing due to vacuum | Re-route tubing to avoid kinks, clear blockage, use thicker wall tubing for vacuum applications |
| Tubing discoloration or hardening | Exposure to incompatible chemicals, excessive temperature, UV exposure | Verify chemical compatibility, ensure temperature limits are not exceeded, protect from UV light, replace tubing |
| Tubing bursting | Exceeding maximum operating pressure, physical damage | Ensure pressure is within limits, inspect for damage before use, replace tubing |
