Flexi hose stainless steel braid - 3/4" FF (19x26); 100cm IVAR.2512

Product detailed description

Stainless steel braided flexi hoses are essential components in heating and plumbing systems where flexibility is required to accommodate pipe movement or misalignment. These hoses are commonly used in residential and commercial buildings for connecting boilers, water heaters, and other heating appliances to pipework. Installers frequently encounter situations where rigid piping cannot be used due to spatial constraints or thermal expansion requirements. The stainless steel braid provides mechanical protection while maintaining flexibility, making it suitable for both hot and cold water systems.

In industrial and residential applications, these hoses are often integrated into systems where vibration or thermal cycling is present. The braiding ensures the hose maintains its integrity under pressure while allowing for angular movement. The internal and external diameters are critical for determining flow characteristics and compatibility with existing pipework. The 100 cm length is a standard size for many installations, though custom lengths are available upon request for specific applications.

Technical parameters

Operating temperature	+110 °C
Nominal pressure	PN 10
Weight	0.54 kg
Code	25122799
Brand	IVAR

The nominal pressure rating of PN 10 indicates the hose is suitable for systems operating at up to 10 bar. The maximum operating temperature of +110°C means it can handle hot water and heating system fluids. These parameters are essential for ensuring the hose is correctly sized for the application and compatible with the system's operating conditions. The internal diameter affects flow rate, while the external diameter determines the space required for installation.

Installation and connection

The hose features female-female thread connections with 3/4 inch internal threads on both ends. Before installation, ensure the threads are clean and free from debris. Apply a suitable sealing compound to the threads to prevent leaks. Carefully align the hose with the fittings and tighten the connections using an appropriate wrench. Avoid over-tightening, which can damage the threads or cause the hose to kink. A common mistake during installation is not allowing enough clearance for movement, which can lead to stress on the connections and potential failure over time.

Compatibility and accessories

This flexi hose is compatible with standard plumbing and heating system fittings that use 3/4 inch internal threads. It is typically used with ball valves, pipe fittings, and other threaded components. When installing, ensure that all connected components are rated for the same pressure and temperature conditions. No additional accessories are required for standard installations, but sealing compounds and thread sealants may be used to ensure a leak-free connection.

Technical background for designers

The hose operates by allowing flexible movement between two rigid pipe sections while maintaining a sealed connection. The stainless steel braid provides structural support and prevents the hose from collapsing under pressure. The material properties of the stainless steel ensure resistance to corrosion and wear, making it suitable for long-term use in water systems. The integration into the system depends on the system's pressure and temperature requirements, as well as the space available for installation. The hose's flexibility allows it to accommodate minor misalignments and thermal expansion without stressing the connections.

Service and operation

During operation, the hose should be inspected regularly for signs of wear, such as cracks in the braid or leaks at the connections. Ensure that the hose is not subjected to excessive bending or kinking, as this can reduce its service life. If the system is shut down for an extended period, it is advisable to drain the hose to prevent the risk of internal corrosion. No specific service intervals are required, but regular visual inspections are recommended to ensure continued performance.

Frequently asked questions
