Stainless Steel Extension Hose PROFI S for Drinking Water with Stainless Steel Fittings (3/4" FF, 50-100 cm)

Product detailed description

Stainless steel extension hoses are commonly used in plumbing and sanitary systems where flexibility and durability are required. They are ideal for connecting taps, valves, and other components in residential, commercial, and industrial buildings. These systems often require precise alignment and frequent adjustments, making a flexible stainless steel solution essential for long-term reliability and leak-free performance.

Installers and technicians working on drinking water systems benefit from the combination of corrosion resistance and mechanical strength offered by stainless steel. This hose is suitable for applications where the medium is potable water and the system is exposed to varying temperatures and pressures. It is particularly useful in tight spaces or where movement of connected components might occur during operation.

Technical parameters

The technical parameters define the operational limits and compatibility of the hose. The 3/4 inch female-female fittings ensure secure and leak-free connections in standard plumbing systems. The operating temperature range of -20°C to +100°C allows the hose to function in both cold and warm water applications. The adjustable length between 500 and 1000 mm provides flexibility for different installation requirements. The hose is certified for drinking water according to the specified hygienic test.

Installation and connection

When installing this stainless steel extension hose, ensure that both ends are correctly threaded and compatible with the connected components. The female-female configuration requires male-threaded fittings on both sides of the hose. Verify that the threads are clean and free from debris before tightening. Use a wrench to secure the connection, but avoid over-tightening which can damage the threads or fittings. A flat gasket is included in the rotating part of the fitting to ensure a watertight seal.

Common installation mistakes include mismatched thread types or incorrect tightening methods. Always confirm that the hose is compatible with the existing system and that the working pressure does not exceed the rated limit. Check for any visible damage to the hose body or fittings before final assembly.

Compatibility and accessories

This hose is compatible with standard drinking water systems using 3/4 inch male-threaded components. For installations requiring different thread configurations, additional adapters or fittings may be necessary. Ensure that all components are made from compatible materials to prevent galvanic corrosion. No related products are specifically recommended for this hose.

Technical background for designers

The hose operates by allowing the stainless steel tube to flex while maintaining a continuous flow path. The material properties of AISI 304L provide high ductility and resistance to corrosion, making it suitable for long-term use in water systems. The fittings, made from AISI 303 stainless steel, are designed for mechanical strength and ease of assembly. Integration into the system should consider the flexibility of the hose and its ability to compensate for minor misalignments. The service life of the hose depends on proper installation, correct operating conditions, and regular inspections for signs of wear or damage.

Service and operation

During operation, ensure that the hose is not subjected to excessive bending or torsion, which can weaken the material or cause kinks. Periodically inspect the connections for leaks and verify that the fittings remain securely fastened. If the hose is exposed to high temperatures or chemical environments, additional protective measures may be necessary. No specific service intervals are provided in the brief, but routine checks are recommended as part of standard maintenance procedures.
