A Brief Overview Of What Dry Disconnect Couplings Are For

Spills and releases due to accidental hose disconnection are common in many industrial facilities. Not only are these accidents inconvenient, but they can also cost a lot, especially if significant operations are halted because of them. Fortunately, the chances of these accidents occurring can now be greatly reduced or eliminated with the use of dry disconnect couplings. In this article, we share all you need to know about dry disconnect couplings in Singapore and their typical industrial applications. 


What are dry disconnect couplings?

Dry disconnect couplings (also known as dry break couplings) are fittings that provide elaborate fluid handling solutions. They are intentionally made to ensure safe and spill-free filling. Hence, dry disconnect couplings are considered the gold standard for industrial refuelling and fluid transfer these days because they are robust, reliable, and purposely designed to endure the rigours of daily use – even in the most extreme worksite conditions. 


How do dry disconnect couplings work? 

Dry disconnect couplings are called a ‘coupling’ due to the fact that they consist of two separate components (i.e. a dry break receiver and a dry break nozzle) that lock together to create a wholly sealed conduit for the cost-effective, clean, efficient, and secure transfer of oils, fuels, and other liquids. A dry disconnect coupling typically has internal mechanical valves that stay closed until the mating valves are entirely connected, at which point an optimum fluid pathway opens.

After the completion of the filling, either via an automatic shutdown feature or by an operator, the valves are then closed, and the fluid pathway is fully sealed just before uncoupling the mating halves so that spills and leaks are minimised – this is where the ‘dry’ aspect of this tool’s name comes from. The dry disconnect coupling separates into two fluid-tight parts.


Common applications of dry disconnect couplings

Dry disconnect couplings are available in a variety of connection types and sized fittings that are suitable for an array of applications. Usually, dry disconnect couplings are utilised in mining and other heavy industrial refuelling applications since they provide advanced security and protection against accidental spills of valuable liquids and minimise concerns with regard to the financial and environmental impacts of hydrocarbon spillage.

Aside from mining, the applications of dry disconnect couplings are typically found in industries such as construction, railways, ports, and agricultural operations. Due to this, it is crucial for dry disconnect couplings to be constructed in such a way as to operate effectively even in harsh climates or extreme conditions. Alongside service fluid transfer, oil refuelling, and evacuation on mobile plants and heavy vehicles, dry disconnect couplings can also be used in premium mechanical tank overfill prevention products.



All in all, dry disconnect couplings are an excellent solution to one of the major problems faced by many industrial facilities – accidental spillage. With their robust design and smart mechanisms, dry disconnect couplings can successfully facilitate safe fluid transfer and refuelling across a variety of heavy industries. This excellent fluid handling solution is also highly recommended for those companies that wish to implement more environmentally conscious operations.
