Flexi hose stainless steel braid - 5/4" FM (32x42); 50cm IVAR.2511

Product detailed description

Stainless steel braided flexi hoses are essential components in the installation of heating, plumbing, and sanitary systems. These hoses are commonly used in residential, commercial, and industrial buildings where reliable and flexible connections are required. They are particularly useful in situations where rigid piping is impractical or where movement between connected components must be accommodated. Installers and technicians working on boiler systems, underfloor heating, and water supply lines often rely on these hoses for their flexibility and durability.

Proper selection and installation of a flexi hose is critical to ensure system integrity and long-term performance. The hose must be compatible with the system's operating pressure and temperature, and the correct thread type and size must be used to ensure a secure connection. The stainless steel braid provides reinforcement, enhancing the hose's resistance to kinking and mechanical stress during installation and operation.

Technical parameters

The nominal pressure rating of PN 10 indicates that the hose is suitable for systems operating at up to 10 bar. The operating temperature of +110 °C makes it suitable for hot water and heating applications. These parameters are essential for determining the hose's suitability for a specific installation and for ensuring that it meets the required safety and performance standards.

Installation and connection

When installing this flexi hose, ensure that the internal and external FM threads are compatible with the connected components. The hose should be tightened securely using an appropriate wrench to prevent leaks. It is important to avoid over-tightening, which can damage the threads or the hose itself. Before final tightening, check that the hose is not kinked and that it is aligned correctly with the connected fittings. Common installation mistakes include using the wrong thread type or failing to check for kinks, both of which can lead to leaks or reduced flow.

Compatibility and accessories

This stainless steel braided flexi hose is compatible with standard FM-threaded fittings and valves used in heating and plumbing systems. When installing, ensure that all connected components are rated for the same pressure and temperature. Additional accessories such as unions, valves, and fittings may be required depending on the system configuration. No related products are specified for this model.

Technical background for designers

The hose operates by allowing flexible movement between connected components while maintaining a secure seal. The stainless steel braid provides reinforcement and structural integrity, preventing collapse under pressure. The hose is suitable for use with potable water and is certified for such use. The service life and efficiency of the hose depend on correct installation, regular inspection, and the absence of mechanical stress or kinking during operation.

Service and operation

During operation, the hose should be inspected periodically for signs of wear, kinking, or leakage. No specific service intervals are provided for this model. If any issues are detected, the hose should be replaced immediately to prevent system failure. It is important to ensure that the hose remains free from mechanical stress and that it is not subjected to excessive bending or twisting during operation.
