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

Product detailed description

Stainless steel extension hoses are commonly used in residential and commercial plumbing systems where flexibility and hygiene are essential. These hoses are frequently found in connections between water supply lines and fixtures such as taps, valves or appliances. Their ability to extend allows for adjustments during installation or maintenance, accommodating minor misalignments or space constraints. In heating and sanitary systems, they ensure reliable flow while maintaining compliance with drinking water standards.

In industrial and residential settings, these hoses are often integrated into systems requiring periodic disassembly for cleaning or inspection. Their resistance to corrosion and compatibility with flat gaskets make them ideal for tight sealing in wet environments. Installers should consider the operating temperature range and ensure that the hose is correctly sized for the required flow and pressure conditions.

Technical parameters

Installation and connection

Installation involves connecting the hose to components with matching 1 inch internal threads. The hose can be stretched to double its original length, so it is important to allow sufficient slack during initial assembly. To connect, align the hose with the threaded component and hand-tighten before using a wrench to secure it. Ensure the flat gasket is properly seated to prevent leaks. Always verify the alignment of the hose before tightening to avoid stress on the fittings.

Compatibility and accessories

This hose is compatible with standard 1 inch internal thread fittings used in drinking water systems. For installations requiring different thread types, additional adapters may be necessary. Ensure that the system components, such as valves or taps, are also rated for the same temperature and pressure range. No specific accessories are required for standard installation, though flat gaskets may need to be replaced periodically depending on usage conditions.

Technical background for designers

The hose operates by stretching along its length while maintaining structural integrity due to the high ductility of AISI 304L stainless steel. The material’s resistance to corrosion and ability to maintain hygiene make it suitable for potable water systems. The fittings are made of AISI 303 stainless steel, chosen for its machinability and compatibility with the threading standard EN 10226-1. When integrated into a system, the hose should be positioned to allow free movement and avoid kinking. The service life is influenced by the frequency of stretching, exposure to aggressive chemicals and the quality of the sealing gaskets.

Service and operation

Periodic visual inspections are recommended to check for signs of wear, such as cracks or deformation in the hose body or fittings. Ensure that the connections remain leak-free and that the flat gaskets are intact. If the hose becomes kinked or damaged, it should be replaced immediately to prevent failure. There are no specified service intervals, but regular checks during maintenance routines are advisable. Avoid exposing the hose to temperatures beyond its stated range, as this can compromise its structural properties.
