Emco Wheaton - DRY-BREAKTM Couplings
Petroleum, petrochemical and industrial markets have used Emco Wheaton DRY-BREAKTM couplings to safely and efficiently transfer fluid for over 30 years.
The specially designed interlock feature in each coupler ensures that the coupler cannot be opened until securely attached to the adaptor.
Once coupled and opened, the coupler cannot be removed until the valve is completely closed, eliminating the risk of nasty spills that endanger personnel and the environment.
To ensure that you select the correct DRY-BREAKTM coupling for your application please use the part number matrix below.
