The French Mold Nickel Plated Brass 135 Degree Plug Quick Disconnect Coupling is a high-quality connector engineered to deliver efficient and reliable performance in industrial cooling and fluid transfer systems. Adhering to the French mold standards (NF EN 14420-1) and Staubli standard, this coupling is designed to meet the rigorous demands of various industrial applications.
Its 135-degree angled plug is a standout feature, as it aligns perfectly with the natural routing of hoses, effectively reducing kinking and strain. This not only extends the lifespan of the hoses but also ensures smooth fluid flow. Crafted from C3604 brass with a 5μm nickel plating that complies with ASTM B633 standards, the coupling boasts exceptional resistance to rust, oxidation, and chemical corrosion, making it suitable for use in harsh and demanding environments.
The quick-release mechanism is another key advantage, enabling one-handed operation for fast and easy connections and disconnections without the need for tools. This feature is particularly valuable in situations where frequent system adjustments or emergency shut-offs are required. With its compact design and leak-proof sealing, the coupling guarantees reliable performance, ensuring zero leakage even under working pressures up to 10 bar (145 PSI).

The use of C3604 brass as the base material provides a strong and durable foundation for the coupling. The addition of a 5μm nickel plating enhances its performance by offering excellent resistance to rust, oxidation, and chemical corrosion. This plating meets the stringent ASTM B633 standards, ensuring that the coupling can withstand the harsh conditions of industrial environments, including wet and acidic settings, thus extending its service life.
Equipped with a spring-loaded collar and internal ball bearings, the quick-release locking system ensures a secure and reliable connection. The collar can be easily pushed and pulled, allowing for instant connection and disconnection with one hand, eliminating the need for tools. An audible "click" confirms that the coupling is fully engaged, preventing accidental disconnection even under pressure, which is crucial for maintaining system safety and efficiency.
The coupling incorporates a dual sealing mechanism to ensure leak-proof performance. The primary O-ring (standard NBR or optional FKM) provides an effective seal against fluid leakage, even at working pressures up to 10 bar (145 PSI). When disconnected, a secondary dust cap prevents contamination of the sealing surfaces, ensuring that the coupling remains clean and ready for use, which helps to maintain its performance and reliability over time.
Designed to comply with NF EN 14420-1 (G thread), the coupling is fully compatible with French-style sockets and hoses commonly used in European mold cooling systems. Available in sizes G1/4", G3/8", and G1/2", it can fit standard coolant lines, making it a versatile choice for a wide range of industrial applications that follow French mold standards.
In mold cooling systems, such as those used in injection molds, blow molds, and die-casting tools, the coupling plays a vital role. It enables quick and easy changes of coolant lines during mold swaps, reducing downtime and increasing productivity. The 135-degree angle design ensures that the hoses can be routed smoothly, avoiding kinking and ensuring efficient coolant flow, which is essential for maintaining optimal mold temperatures and product quality.
Within CNC machine tools, the coupling is used in spindle and axis cooling circuits. The angled design simplifies hose routing around moving machine components, preventing interference and reducing the risk of hose damage. This ensures that the cooling system can operate effectively, maintaining the proper temperature of the machine parts and ensuring stable and accurate machining operations.
For mobile hydraulic equipment, including construction machinery like excavators and loaders, and agricultural machinery, the coupling offers a convenient solution for fast hose connections in hydraulic power units. Its quick-release mechanism allows for easy maintenance and repair, reducing the time spent on equipment downtime. The durable construction and resistance to harsh environments make it suitable for use in outdoor and rugged conditions.
In industrial water treatment systems, such as filtration systems and heat exchangers, the coupling facilitates maintenance by enabling rapid hose disconnection. This allows for easy cleaning or replacement of components, ensuring that the system operates efficiently and effectively. The leak-proof sealing and corrosion resistance ensure that the coupling can withstand the water and chemical environments encountered in these applications.
