Gas Handling & Ancillary Equipment

DCG Partnership strives to offer our customers with single source for gases, gas handling equipment and accessories. We have a wide variety of valves, regulators, switchover manifolds, heated products, and accessories.


The Compressed Gas Association has selected and standardized the valve outlet to be used on each gas cylinder. These reference materials contained in the document CGA Reference Material V-1, Compressed Gas Cylinder Valve Outlet Connections, have been adopted to prevent inadvertent mixing of gases. Different CGA connections are required depending upon the properties of the gas. Brass is for non-reactive gases and Stainless Steel is for reactive gases.
