Kottmann – Supply hoses

For more than 15 years now, Kottmann´s flexible supply hoses have proven a success in the sanitary and heating industry. Recent developments and technologies have led to new cer- tifications and extended requirements – for pressure hoses.

Tod, the Kottmann technology highly popular with our customers meets the latest technical requirements and all important global drinking water certifications. The hoses are also PAH- free, REACH-compliant and available with lead-free and low lead brass materials.

These days, this type of flexible hose is produced primarily using
the Kottmann technology due to its huge technical benefits. Customers can also choose from all the customary inliners, such as TPE, silicone, EPDM or Pex.
