Stainless Steel Extension Hose PROFI S for Drinking Water with Stainless Steel Fittings (1/2" FM, 75-150 cm)

Product detailed description

Stainless steel extension hoses are commonly used in residential and commercial plumbing systems where flexibility and durability are required. These hoses are ideal for connecting fixtures such as taps, valves and appliances to the main water supply. The PROFI S model is designed for use with drinking water and provides reliable performance in both cold and warm water applications. It is particularly suited for installations where space constraints require an adjustable length solution.

The hose is available in lengths between 750 mm and 1500 mm, allowing it to be selected according to the specific requirements of the installation. Its flexible design enables it to be stretched up to twice its original length, making it suitable for tight spaces. The FM thread configuration allows for secure connections between components with internal and external threads. The hose is constructed using high-quality stainless steel materials, ensuring long-term reliability and resistance to corrosion.

The technical parameters listed define the operating limits and compatibility of the hose. The working temperature range of -20 °C to +100 °C ensures the hose can be used in both cold and warm water systems. The FM thread configuration allows for secure and leak-free connections in mixed-thread applications. The hose length options allow for precise selection based on the distance between the connection points. The material grades ensure the hose meets the mechanical and chemical resistance requirements for drinking water systems.

Installation and connection

To install the hose, first ensure that the system is depressurised. Clean the threads of both the fitting and the connection point to remove any debris. Apply a suitable sealing compound or PTFE tape to the male thread. Insert the hose into place and hand-tighten the connection before securing it with a wrench. Ensure that the hose is not twisted during installation and that it is not stretched beyond its maximum recommended length. Common installation errors include over-tightening the fittings, which can damage the threads, and failing to clean the connection surfaces before assembly. Always verify that the hose is compatible with the system pressure and temperature conditions before commissioning.

Compatibility and accessories

This hose is compatible with standard plumbing fittings that accept 1/2 inch FM thread connections. It is suitable for use in drinking water systems where flexibility and durability are required. Additional components such as valves, taps and pressure regulators may need to be ordered separately depending on the installation requirements. The hose should be used in conjunction with appropriate sealing materials to ensure a leak-free connection.

Technical background for designers

The hose operates by allowing the flexible stainless steel tube to expand and contract while maintaining a sealed connection at both ends. The AISI 304L stainless steel tube provides high flexibility and resistance to deformation under normal operating conditions. The AISI 303 fittings offer good machinability and corrosion resistance, making them suitable for repeated installation and removal. The design allows for integration into both new and existing plumbing systems. The service life of the hose is influenced by factors such as the frequency of installation changes, exposure to aggressive chemicals and the quality of the connection surfaces. Proper sizing and selection based on the application requirements are essential to ensure efficient and long-term performance.

Service and operation

During regular operation, inspect the hose for signs of wear, deformation or leakage. Check the integrity of the connections and ensure that the hose is not subjected to excessive bending or stretching. There are no specific service intervals provided in the technical documentation, but periodic inspections are recommended as part of routine maintenance. If any damage is detected, the hose should be replaced immediately to prevent potential failures. Always follow the manufacturer's guidelines for safe handling and storage.
