Dry Disconnect Couplings

Dry Dis­con­nect Cou­plings are the given choice for handling any liquid, chem­i­cals, gas.

The stan­dard­ized in­ter­face to STANAG 3756 with its bayonet coupling prin­ci­ple has been widely accepted in the industry. Ap­pli­ca­tion for in­dus­tri­al process plant, road and rail tankers, IBC con­tain­ers, phar­ma­ceu­ti­cal and petro­chem­i­cal in­dus­tries etc.

Avail­able with threaded and flanged con­nec­tions, for both hose unit and tank unit.
