Emco Wheaton DRY-BREAK couplers and DRY-BREAK adapters are designed for total safety. Fluid cannot flow until the Emco Wheaton coupler has been locked into position on an Emco Wheaton Adapter and the valve opened. The coupler can only be disconnected from the adapter when the valve has been closed. Since product loss is thereby eliminated, possible hazards associated with leakage at disconnect are no longer a concern. DRY-BREAK couplers and adapters are rated for a working pressure of 85 psi (PN 6) and are available in sizes ranging from 1-inch up to 3-inch in diameter with a variety of body construction and seal materials available.
