Flexi hose stainless steel braid - 3/4" FF (19x26); 50cm IVAR.2512

Product detailed description

Stainless steel braided flexi hoses are essential components in heating and plumbing systems, particularly in residential and commercial buildings. These hoses are commonly used to connect radiators, boilers, and other heating appliances to pipework. The flexibility of the hose allows for easier installation in tight spaces and accommodates minor misalignments between components. The hose is suitable for both heating and potable water systems, making it a versatile solution for a range of applications.

When installing such systems, professionals must ensure that the hose is compatible with the pressure and temperature conditions of the system. The hose must also be correctly sized to avoid flow restrictions or excessive stress on the connections. The stainless steel braid provides additional durability and resistance to mechanical damage, ensuring long-term performance in demanding environments.

Technical parameters

Installation and connection

Installation of the stainless steel braided flexi hose involves connecting the female-female threads to the corresponding fittings on the system components. The hose length of 50 cm allows for sufficient reach in most installations. It is important to ensure that the threads are clean and free of debris before tightening to prevent leaks. A common mistake is over-tightening the connections, which can damage the threads or cause the hose to kink. Installers should also verify that the hose is not twisted during installation, as this can affect flow and reduce the hose's lifespan.

Compatibility and accessories

This hose is compatible with standard heating and plumbing systems that use female-female thread connections. It is typically used in conjunction with ball valves, radiators, and other components that require a flexible connection. When ordering, it is important to ensure that the system components are also rated for the same pressure and temperature conditions. Additional accessories such as unions or adapters may be required for specific installations, depending on the system configuration.

Technical background for designers

The stainless steel braided flexi hose operates by allowing flexible movement between connected components while maintaining a secure and leak-free connection. The hose is constructed with an inner rubber or EPDM tube, a stainless steel braid for reinforcement, and an outer protective layer. The stainless steel braid provides resistance to mechanical stress and prevents the hose from collapsing under pressure. The hose is integrated into the system by connecting the female threads to the corresponding fittings. The operating temperature and pressure ratings are influenced by the materials used and the system's hydraulic conditions. Proper sizing and installation are essential to ensure efficient operation and prevent premature failure.

Service and operation

During operation, the hose should be inspected periodically for signs of wear, such as cracks, kinks, or leaks. Any damage to the hose should be addressed immediately to prevent system failure. The hose does not require regular maintenance beyond visual inspection, as it is designed for long-term use. If the system is shut down for an extended period, it is advisable to drain the water to prevent corrosion or freezing damage. There are no specified service intervals for this product, but it should be replaced if any defects are detected.

Frequently asked questions

Can this hose be used in a central heating system?
Yes, the hose is suitable for central heating systems due to its pressure and temperature ratings. It is commonly used to connect radiators and boilers.

Can the hose be cut to a different length?
No, the hose is manufactured in fixed lengths. Custom lengths such as 30 cm and 70 cm are available upon request.

What is the difference between the internal and external diameter values?
The internal diameter (19 mm) refers to the size of the hose's inner tube, while the external diameter (26 mm) refers to the overall size of the hose including the stainless steel braid.
