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

Product detailed description

Stainless steel extension hoses are commonly used in residential and commercial plumbing systems to connect fixtures, valves, and fittings in potable water supply lines. These hoses are particularly suited for applications where flexibility and durability are required, such as in kitchens, bathrooms, and industrial water distribution systems. The design allows for expansion and contraction during installation, accommodating slight misalignments and ensuring a secure connection. The material choice and construction ensure compliance with hygiene standards for drinking water, making them suitable for use in both new installations and system upgrades.

When working with potable water systems, installers must ensure that all components meet local regulations and standards. The stainless steel construction of this hose provides resistance to corrosion and scaling, which is essential for maintaining water quality over time. The hose is also designed to handle a wide range of operating temperatures, making it suitable for both hot and cold water applications. Its flexibility allows for easier routing around obstacles, reducing the need for additional fittings and joints that could compromise the system's integrity.

Technical parameters

The technical parameters define the hose's suitability for specific applications. The 1 inch FM thread configuration ensures compatibility with standard fittings and valves in potable water systems. The operating temperature range of -20°C to +100°C allows the hose to be used in both cold and hot water environments. The material properties of AISI 304L and AISI 303 ensure resistance to corrosion and mechanical stress, making the hose suitable for long-term use in demanding conditions.

Installation and connection

Installation of the stainless steel extension hose requires attention to thread alignment and sealing. The FM configuration (one internal and one external thread) allows for secure connections to both male and female fittings. Before installation, ensure that the threads are clean and free from debris to prevent leaks. Apply a suitable sealing compound or tape to the threads to ensure a watertight connection. The hose can be stretched to twice its original length, so it is important to select the appropriate size based on the required expansion range. Common installation mistakes include over-tightening the fittings, which can damage the threads, and using incompatible sealing materials that may degrade over time.

Compatibility and accessories

This hose is compatible with standard potable water fittings and valves that accept 1 inch FM threads. It is designed for use in systems that require a flexible connection between components, such as between a water supply line and a fixture or valve. No additional accessories are required for installation, as the hose is supplied with the necessary fittings. However, it is important to verify that the system components are also rated for the same operating conditions, including temperature and pressure. Related products include other stainless steel hoses with different thread configurations and lengths, which may be required for specific installation needs.

Technical background for designers

The operating principle of the stainless steel extension hose is based on the flexibility and elasticity of the material. The AISI 304L tube allows for controlled expansion and contraction, accommodating movement in the system without compromising the integrity of the connection. The AISI 303 fittings provide a secure and durable connection, with a flange for flat gasket sealing in the rotating section. The material properties of the stainless steel ensure resistance to corrosion and scaling, which is essential for maintaining water quality in potable systems. The hose is integrated into the system by connecting it to the supply line and the fixture or valve, ensuring that the connection is secure and leak-free. The service life and efficiency of the hose are influenced by factors such as operating temperature, pressure, and the presence of aggressive substances in the water.

Service and operation

Regular inspection of the hose and its connections is recommended to ensure continued performance. Check for signs of wear, corrosion, or leakage, particularly at the fittings. If any issues are detected, the hose should be replaced to prevent system failure. No specific service intervals are provided, but it is advisable to inspect the hose during routine maintenance of the water system. The hose should be kept clean and free from debris to prevent blockages and ensure smooth operation. In the event of a leak or damage, the hose should be disconnected and replaced with a new unit of the same specifications.

Frequently asked questions

Can the hose be used in hot water systems?
Yes, the hose is suitable for hot water systems with operating temperatures up to +100°C.

What is the maximum working pressure of the hose?
The hose is rated for a maximum working pressure of 10 bar, making it suitable for standard potable water systems.

Can the hose be stretched beyond its maximum length?
No, the hose should not be stretched beyond twice its original length, as this may cause permanent deformation or failure.

Is the hose compatible with flat gasket sealing?
Yes, the fittings are designed with a flange for flat gasket sealing, ensuring a secure and leak-free connection.
