Brass threaded fittings are used to make demountable connections in heating, water and other installations where there is a non-aggressive working medium. Threaded fittings were designed by our engineers, who, taking into account the convenience of their use - placed special ribs and concave inscriptions on their surface, so that tightening them with a wrench is easier. In addition, the external threads in our threaded fittings are knurled - for easier application of sealing materials. Threaded connectors meet the requirements of EN 1254-4.
