Stainless Steel Extension Hose PROFI S for Drinking Water with Stainless Steel Fittings (1" FM, 100-200 cm)

Product detailed description

Stainless steel extension hoses are commonly used in industrial and commercial plumbing systems where flexibility and durability are required. These hoses are typically found in applications such as water supply lines, where the ability to extend and contract is necessary to accommodate movement or misalignment in the installation. The PROFI S model is particularly suited for drinking water systems, ensuring compliance with hygiene standards while maintaining mechanical integrity under variable thermal conditions.

In building services, these hoses are often integrated into supply lines for kitchens, laboratories, and filtration units. The design allows for easy installation and adjustment during commissioning or maintenance. Installers must ensure correct alignment and secure fitting connections to prevent leakage and maintain system performance. The material choice ensures resistance to corrosion and long-term stability in fluctuating temperature environments.

The technical parameters define the hose's suitability for specific applications and system conditions. The operating temperature range (-20°C to +100°C) ensures compatibility with both cold and warm water systems. The 1 inch FM configuration indicates one female and one male thread, facilitating direct connection to standard pipe fittings. The hose can extend to twice its original length, accommodating dynamic installation requirements. These parameters are essential for determining correct hose size and fitting type during system design and installation.

Installation and connection

Installation involves connecting the hose between two threaded components using the FM configuration. The 1 inch thread must align with the corresponding mating component. Prior to tightening, ensure the sealing surfaces are clean and free from debris. Apply a suitable lubricant if required by the manufacturer’s guidelines. The hose should be positioned without kinking or twisting, and the fittings tightened to the recommended torque to avoid over-tightening, which can damage the threads or the hose itself.

Common installation errors include mismatched thread types, incorrect orientation of the FM configuration, and failure to allow for expansion. Check that the hose is fully seated in the fittings and that the system allows for the hose’s maximum extension. Avoid exceeding the maximum working pressure of 10 bar and ensure the operating temperature remains within the specified range to prevent material degradation.

Compatibility and accessories

This hose is compatible with standard drinking water systems using 1 inch threaded components. It is suitable for use with flat gaskets in rotating fittings, as defined by the EN 10226-1 standard. When installing, ensure that all connected components are also rated for the same operating conditions. Additional components such as unions, valves, or pressure regulators may be required depending on the system layout. No specific related products are listed for this model.

Technical background for designers

The hose operates by allowing axial movement between connected components, compensating for thermal expansion or mechanical misalignment. The AISI 304L tube provides high ductility and resistance to stress corrosion cracking, making it suitable for fluctuating loads and temperatures. The AISI 303 fittings offer good machinability and wear resistance, ensuring reliable sealing under repeated use. Integration into the system requires careful consideration of the hose’s extension capability to avoid overstressing the material or fittings. Long-term efficiency depends on correct installation, proper alignment, and adherence to operating limits.

Service and operation

During operation, inspect the hose regularly for signs of wear, corrosion, or leakage. Check the tightness of the fittings and the condition of the sealing surfaces. Ensure the hose is not subjected to excessive bending or lateral forces, which can cause premature fatigue. No specific service intervals are provided in the technical documentation, but maintenance should be carried out in accordance with the system’s overall service schedule. Replace the hose if any damage is detected or if it no longer meets the required performance criteria.
