Non-spill quick disconnect couplings are designed to reduce spillage to near zero whenever they’re disconnected. They were originally designed as heavy-duty fittings for high-pressure, industrial hydraulic applications, but as more low-pressure uses for non-spill connectors emerged, it became clear that high-pressure fittings were over-engineered and too costly.

Today, a new category of couplings has evolved. It consists of low-pressure, small footprint thermoplastic and metal fittings that maintain non-spill performance characteristics. They are used for a variety of low pressure, fluid-handling applications that require minimal spillage.

There are six beneficial traits of low-pressure, non-spill fittings including:

• The inclusion of non-spill, flush-faced valves
• The use of engineered polymers for reduced weight and high strength
• Design features that deliver low air inclusion and minimal pressure drop
