Emco Wheaton DRY-BREAK

Emco Wheaton DRY-BREAK couplers and adaptors have a specially designed interlock feature in each coupler which ensures that they cannot be opening 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-BREAK coupling for your application, please use the part number matrix below.
