Reliability for Daily Use in the Kitchen and Bathroom

Our high-quality shower hoses are designed for maximum reliability and a long service life in daily use. Whether as a shower hose, a pull-out kitchen hose, or a commercial hose in professional commercial kitchens, they consistently deliver the highest level of functionality and safety.

The agraff profile with a silicone inner liner—developed specifically for these applications—combines outstanding flexibility with high tensile strength. Thanks to the patented connection technology, the inner liner, which comes into contact with drinking water, is permanently bonded to the metal spiral, which bears the mechanical stress. The result is a particularly tensile-strong solution with a high-quality feel and appearance.

As an established OEM partner, Witzenmann supplies numerous leading international faucet manufacturers with customized solutions. In addition to classic chrome-plated shower hoses, we fulfill individual customer requests, including powder coatings, PVD finishes, and other exclusive design variations. Thanks to our many years of experience in project-based business, we also offer a wide range of customization options: these include customer-specific union nuts, connection fittings, laser markings, and other brand-specific design elements to ensure high brand recognition for your products.

Of course, our products meet all relevant drinking water and hygiene requirements.

Questions and Answers

A shower hose typically has the following construction:

Water-contacting inner liner—always made of silicone at Witzenmann!
Cone with EPDM O-ring
Agraff coiled tubing made of stainless steel or brass
Custom connection fittings (G1/2'', G3/8'' female thread) for kitchen pull-out hoses with M12 or M15 threads
Sleeves for connecting the inner liner to the Agraff-wound hose

Witzenmann manufactures only high-quality metal shower hoses. Plastic hoses are not included in our product lineup.

A metal shower hose is made of either brass 2.0321 (CW508L) or stainless steel 1.4301. The brass is then nickel-plated or chrome-plated. Stainless steel is also available in its uncoated form. This finish is a popular choice, particularly for pull-out kitchen hoses and in commercial kitchens.

Of course, we can also provide custom finishes (electropolished, PVD, powder coating).

Shower hoses meet the requirements of DIN EN 1113.
Kitchen exhaust hoses meet the requirements of DIN EN 16146.

Witzenmann shower hoses comply with the EU Drinking Water Directive 2020/2184 and Delegated Regulation 2024/370. (dwd). All parts that come into contact with water comply with KTW-BWGL, ACS, and WRAS.
