For the correct selection and assembly of compression fittings, please refer to the GOK assembly manual and the data sheets for compression fittings and screw-in connectors (at www.gok.de/en/data-sheets or www.gok.de/en/installation-instructions). If you are installing a compression fitting with copper or aluminium pipe, you must use a reinforcement ring. For aluminium pipes, use a reinforcement ring made of steel! All compression fittings are approved by the DVGW.
