Description
he COLDFLEX 504 is a professional-grade crimping tool, specialized for use with the 5 mm Cold-Flex Capillary Hose
| Feature Category | Detail |
| Product Type | Manual Hydraulic Crimping Tool |
| Item Code | COLDFLEX 504 |
| Hose Compatibility | 5 mm Cold-Flex Capillary Hose |
| Included Components | Sold with specific dies designed for the 5 mm Cold-Flex fittings. |
| Mechanism | Manual Hydraulic, meaning the user pumps a lever/handle to generate the immense force required for crimping. |
| Key Function | To create a permanent, leak-tight, high-pressure seal between the 5 mm hose and the metal fittings. |
| Reliability Feature | Provides a highly consistent crimp quality, which is crucial for the 5 mm hose to maintain its 400 bar burst pressure rating in AC/R systems. |
| Distinction from 500 | The 504 is a manual hydraulic tool (requiring human pumping), whereas the 500 is often a rechargeable (powered) hydraulic tool. Both are designed for the 5 mm hose. |
The technical significance of the COLDFLEX 504 lies in its ability to generate the necessary force to compress the fitting sleeve onto the 5 mm hose without reliance on electric power, ensuring high-quality, professional crimps in the field.
- Force: Generates the high hydraulic force (typically measured in tons) required to deform the metal fitting sleeve onto the polyamide hose.
- Pressure Assurance: Use of the 504 is required to ensure the finished hose assembly meets the 50 bar Working Pressure standard for modern refrigerants.
