Description
Features
Dry couplings are fittings specially developed to increase safety during the transport or unloading of hazardous products in order to make these operations more economical, safe and environmentally friendly. They are easy to use and can be used in almost any industrial application due to the different materials available. Dry couplings are especially used in chemical, petrochemical and pharmaceutical industries. The coupling diameters 2″ (KD70) to 4″ (KD164) are manufactured according to NATO STANAG 3756 and are compatible with other brands.
