Stainless Steel Extension Hose PROFI S for Drinking Water with Stainless Steel Fittings (1" FF, 75-150 cm)

Product detailed description

Stainless steel extension hoses are commonly used in residential and commercial plumbing systems for connecting fixtures, valves and equipment in potable water supply lines. These hoses are frequently installed in kitchens, bathrooms, and industrial facilities where flexibility and durability are required. They are suitable for applications involving water at variable temperatures and pressures, and are often integrated into systems that require frequent disassembly for maintenance or inspection. The design allows for expansion and contraction without compromising the integrity of the connection, making it ideal for use in tight spaces or where movement is expected.

When selecting a stainless steel extension hose for potable water, it is essential to consider the material compatibility, thread type and operating conditions. The hose must be capable of withstanding the expected temperature range and pressure levels while maintaining a secure and leak-free connection. The FF (female-female) configuration is particularly useful when connecting two male-threaded components, ensuring a stable and reliable fit. The hose length must also be chosen to suit the specific installation requirements, allowing for sufficient reach without excessive slack.

The technical parameters of this stainless steel extension hose are essential for proper sizing and selection. The hose is designed for potable water and features a 1 inch FF configuration, making it suitable for connecting two male-threaded components. The operating temperature range of -20 °C to +100 °C ensures compatibility with a wide range of water supply conditions. The hose length can be selected from 750 to 1500 mm, allowing for flexibility in installation. The use of AISI 304L stainless steel for the tube and AISI 303 for the fittings ensures durability and resistance to corrosion, making it suitable for long-term use in water systems.

Installation and connection

When installing a stainless steel extension hose, it is important to ensure that the thread type and size match the components being connected. The FF configuration requires both ends to have internal threads, so the installer must verify that the male-threaded components are compatible. The hose should be connected using a flat gasket in the rotating part of the fitting to ensure a tight and leak-free seal. The hose can be stretched up to twice its original length, so it is important to allow for this expansion during installation. Common installation mistakes include using the wrong thread type, failing to check the sealing surface or not allowing enough space for movement. To avoid these issues, the installer should inspect the threads, ensure the sealing surfaces are clean and free from damage, and allow for the full range of motion required by the application.

Compatibility and accessories

This stainless steel extension hose is compatible with a wide range of potable water systems and can be used with various fittings and valves that feature male-threaded connections. It is particularly suitable for use with valves, taps and other components that require a flexible connection. When installing, it is important to ensure that the sealing gasket is in good condition and properly seated in the fitting. No additional accessories are required for basic installation, but in some cases, a lubricant may be used to ease assembly. The hose is not compatible with non-potable water systems or with components that require a different thread configuration, such as FM (female-male) or MM (male-male) fittings.

Technical background for designers

The stainless steel extension hose operates on the principle of flexibility and durability, allowing it to accommodate movement and expansion in the system. The hose is constructed from AISI 304L stainless steel, which is known for its high ductility and resistance to corrosion. The fittings are made from AISI 303 stainless steel, which provides good machinability and wear resistance. The FF configuration ensures that the hose can be connected to two male-threaded components, making it suitable for use in systems where flexibility is required. The operating temperature range of -20 °C to +100 °C ensures that the hose can be used in a wide range of environments. The hose is also suitable for use in systems that require frequent disassembly for maintenance or inspection, as it can be easily disconnected and reconnected without damage.

Service and operation

During operation, the stainless steel extension hose should be inspected regularly for signs of wear, corrosion or damage. The sealing surfaces should be checked to ensure that the gasket is in good condition and properly seated. If the hose is used in an environment with high temperatures or aggressive chemicals, it may require more frequent inspection. No specific service intervals are provided for this hose, but it is recommended to inspect it during routine maintenance. If the hose shows signs of damage or wear, it should be replaced immediately to avoid leaks or system failure. The hose should also be disconnected and cleaned if it is exposed to contaminants or if it is suspected of being compromised.
