Efficient and safe fluid handling via dry break couplings

In the process industry, fluid handling plays a key role when it comes to efficiency, safety and product quality. Whether it’s chemicals, fuels or food-grade liquids, it’s essential to minimize the risk of spills, contamination and accidental leaks. Dry break couplings are designed to do just that.

Traditional coupling systems can often result in fluid leaks during connection and disconnection, which can lead to production downtime, increased safety risks and unnecessary waste. With dry break couplings, it’s possible to maintain a clean workplace, reduce operating costs and improve the working environment. The dry break coupling system is designed to provide a quick and safe connection between hoses and pipes without exposing the operator to harmful or flammable liquids.

Dry break couplings are specially designed coupling systems that enable quick and safe connection and disconnection of hoses and pipes without fluid spillage. They’re primarily used in industrial sectors where high safety standards and efficient fluid handling are critical, such as the chemical, food, oil and gas, and pharmaceutical industries. Modern dry break couplings are designed to withstand high pressure and aggressive fluids.

The great advantage of dry break couplings is their ability to eliminate spillage, a feature that protects personnel, production equipment and the surrounding environment. Furthermore, the dry break coupling system is designed to prevent contamination of liquids, which is crucial in the food and pharmaceutical industries where product integrity is essential.

Dry break couplings consist of two primary components: a male coupling and a female coupling, also known as "Tank Unit" and "Hose Unit". When both units are connected, an internal valve mechanism is activated, allowing the fluid to flow freely through the coupling. Disconnection is done in a controlled manner, with the valves automatically closing to cut off the flow of fluid without spillage.

Dry break couplings are available in several sizes to match different needs. Here’s an overview of the most common sizes and their primary applications:

• 1" (25 mm): Often used for IBC tanks and smaller process plants where flexible and compact solutions are needed.
• 2" (50 mm): Ideal for the chemical industry, tankers and AdBlue distribution where fast and safe filling is required.
• 2.5" (65 mm): Used in airport operations and on road and rail tankers.
• 3" (80 mm): Often used in the marine industry, oil and gas industry and large tankers.
• 4" (100 mm): Typically used in the offshore oil and gas industry and for bunkering ships where high flow and robustness are important.

The right size depends on several factors, including fluid viscosity, operating pressure and flow requirements. It’s always recommended to contact one of our sales consultants to ensure that the coupling matches the specifications of the specific application.

Dry break couplings prevent fluid spills and contamination, while reducing maintenance needs and increasing reliability.

Yes, many dry break couplings are made from stainless steel or chemical-resistant materials that ensure resistance to aggressive fluids.

No, they’re designed for minimal maintenance. Regular cleaning and inspection ensures a long lifetime.
