6 Traits Of Non-Spill: How Quick Disconnect Couplings Evolved For Low-Pressure Fluid Handling

By Grant Wilhelm, Senior Design Engineer, Colder Products Company

Once the domain of high-pressure hydraulics, non-spill performance is now available in quick disconnect solutions for low-pressure fluid handling in countless products and processes.

The term non-spill, when discussing couplings, describes a specific type of connector meant to reduce spillage to near zero whenever couplings are disconnected. This is often achieved through the design of the valves housed within the coupling body. Originally designed as heavyduty metal couplings for high-pressure, industrial hydraulic applications, non-spill has evolved into a category of plastic and metal connectors suitable for a wide variety of fluid-handling applications requiring minimal spillage and air inclusion.
