Description
| Specification | Detail / Value (Based on 2 mm Series) | Notes |
| Product Name | COLDFLEX 405 | Specific part number in the 2 mm product line. |
| Product Type | Flexible Capillary/Instrumentation Hose | Used for pressure sensing, vibration isolation, and fluid sampling. |
| Color | Orange | The unique color for visual distinction and system coding (e.g., sometimes used for oil lines or specific control circuits). |
| Inner Diameter (ID) | 2.20 mm | The small, consistent internal bore size. |
| Outer Diameter (OD) | 5.65 mm | Optimized for connection to standard |
| Max Working Pressure (WP) | 50 bars ( approx 725psi) | The maximum sustained safe operating pressure for this class of hose. |
| Burst Pressure | Extremely High (Tested to exceed 1000 bars) | Provides a massive safety margin under normal operating conditions. |
| Minimum Operating Temp | Cold Flexible Rating (Typically -20 C or lower) | The material maintains flexibility in cold ambient temperatures, preventing cracking and stiffness. |
| Refrigerant Compatibility | Excellent | Low permeability rating ( for R410A) to ensure system efficiency and safety, meeting EN 1736 standards. |
- Vibration Elimination: The primary function is to provide a flexible link that dampens mechanical vibration from components like compressors, ensuring connected pressure gauges and sensors deliver stable and accurate readings.
- Color Coding (Orange): The distinct color is a key feature for technicians, allowing for quick and unambiguous identification of the purpose or circuit the line is monitoring (e.g., specific oil return, intermediate pressure, or a particular control loop).
- High Pressure Capability: Despite its small size, the hose structure includes reinforcement (braiding) allowing it to safely handle the high-side pressures common in modern refrigeration and air conditioning systems.
- Oil and Refrigerant Resistance: The internal polymer compound is chemically resistant to the fluids and lubricants found within cooling systems, ensuring a long and reliable service life without degradation or leaks.
- Application: Suitable for connecting manometers, pressure transducers, pressure switches, and water flow controls in dynamic, high-vibration, or cold-temperature environments.
