Description
Inferred Technical Data for Cold-Flex 411 (5 mm Hose)
| Specification | Typical Value (Inferred from Industry Standard) | Notes |
| Product | Flexible Hose (Oil Hose Black) | Item code: COLDFLEX-411 |
| Inner Diameter (I.D.) | 5 mm | Confirmed size for the 411 model. |
| Hose Material | Polyamide (Nylon) or similar high-performance polymer. | Required for high-pressure refrigerant compatibility. |
| Refrigerant Compatibility | Suitable for all common non-corrosive refrigerants (R410A, R404A, etc.). | Designed for use in modern AC/R systems. |
| Maximum Working Pressure (WP) | 50 bar (725 psi) | High working pressures are standard for these polyamide hoses, often reaching 50 to 80 bar in similar competitor products (e.g., REFFLEX DN-5.0 is rated for 80 bar). |
| Minimum Burst Pressure | 400 bar (5,800 psi) | Industry standards for 5.0 mm refrigeration capillary hoses require very high burst ratings for safety (often 5 to 8 times the WP). |
| Working Temperature Range | -40 C to +115 C | Must withstand both the cold liquid and hot discharge sides of a refrigeration system. |
| Primary Feature | Excellent Vibration Elimination | Crucial for protecting sensitive control equipment. |
The entire Cold-Flex hose line (including the 5 mm models) is designed to solve common issues in refrigeration and AC units:
- Vibration Control: The high-quality materials are engineered to offer excellent vibration elimination, protecting sensitive components like pressure switches and transducers from mechanical stress.
- Safety and Flexibility: They allow for a safe and flexible connection between main system lines and control equipment.
- Cost Efficiency: Using flexible connections is marketed as a factor in cost reduction due to ease of installation and maintenance.
- Material: They are typically made from Polyamide (Nylon) or similar high-performance polymers to withstand the high pressures and temperature cycles of refrigerants like R410A.
