Stainless steel expandable plastic-coated drinking water hose PROFI MW with brass end caps (1/2" FF, 60-120 cm)

Product detailed description

This stainless steel drinking water hose is commonly used in residential and commercial plumbing applications where adjustable-length connections are required. It is suitable for potable water supply lines, such as those found in kitchens, bathrooms, and under-sink filtration systems. The expandable design allows for quick and flexible installation in tight spaces or where alignment adjustments are necessary.

The hose is particularly useful in situations where rigid piping is impractical or where temporary or semi-permanent connections are needed. Its plastic-coated surface provides additional protection against mechanical damage and abrasion during handling or installation. The brass fittings ensure a durable and corrosion-resistant connection to standard plumbing fixtures or valves.

Technical parameters

The hose is rated for a maximum operating temperature of 110°C and a working pressure of 10 bar. These parameters are critical when selecting the hose for specific applications, ensuring it can handle the thermal and hydraulic conditions of the system. The expandable feature allows the hose to stretch between 300 mm and 600 mm, making it adaptable to various installation requirements.

Installation and connection

Before installation, verify that the hose is free from kinks or deformations that could restrict flow or cause premature failure. Ensure that both ends have internal threads (FF configuration) and that the fitting sizes match the connected components. The hose should be stretched to the required length during installation and secured using standard plumbing techniques.

Common installation errors include over-stretching the hose beyond its rated limits or installing it in systems with higher pressure or temperature than specified. Always check that the hose is compatible with the media being transported and that the fittings are properly sealed to prevent leaks.

Compatibility and accessories

This hose is compatible with standard plumbing systems that use 1/2 inch internal thread fittings. When integrating into a system, ensure that all connected components are also rated for the same pressure and temperature levels. Additional components such as valves, filters, or shut-off devices may need to be sourced separately depending on the application.

Technical background for designers

The hose is constructed from austenitic stainless steel (AISI 304L), known for its high ductility and expansion capabilities. This material is selected for its resistance to corrosion and suitability for potable water applications. The plastic coating is made from polyolefin, which provides an outer layer that protects against mechanical stress and environmental factors.

When designing a system, consider the hose’s expansion range and ensure that the installation allows for movement without imposing excessive bending or strain. The hose should be integrated in a way that maintains the integrity of the system and avoids exposure to conditions that exceed its operational limits.

Service and operation

During regular operation, inspect the hose for signs of wear, such as cracks, abrasions, or leaks around the fittings. Ensure that the plastic coating remains intact and that the hose is not subjected to excessive bending or twisting. If any damage is observed, the hose should be replaced immediately to avoid potential failures.
