Product description


The dry couplings are connectors that are especially developed in order to increase safety during the transport or unloading of hazardous products, with the objective of making these operations more economical, safe and respectful to the environment. They are easy to use and can be used in almost any industrial application due to the different materials available. The dry couplings are particularly used in the chemical, petrochemical and pharmaceutical industry. The coupling diameters of 2″ (KD70) to 4″ (KD164) are manufactured in accordance with the NATO STANAG Standard 3756 and are compatible with other brands.
