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.
