Swiftech’s newest entry in the Lok-Seal? family of high-end fittings is a new type of Quick Disconnect Non-Spill fitting, called the QC-NS series, and based on a sliding-sleeve style hydraulic coupling design. The Flush Face mating valves design allows users to connect or disconnect a line with little or no coolant spillage. This new generation of couplings represents yet another breakthrough innovation in the world of quick-disconnect fittings for two reasons:

• At similar flow-rate characteristics, they are substantially more compact than most types of couplings from competing brands, thus offering precious space savings in space-constrained applications.
• A world’s first innovation, Swiftech couplings can be completely disassembled. As a result, they can be configured with multiple types of end caps, thus offering considerable cost savings: there is no need to purchase multiple bodies with specific fittings for different applications: just unscrew the end cap of your QC-NS coupling and replace it with the type of fitting that you need for your new application.

This radically different design concept has two direct consequences:

• Swiftech’s couplings requires a firm push-and twist motion to connect or disconnect due to the reduced fitting length.
• They necessitate that the end caps be correctly fastened prior to being placed in service so that they will not loosen when being operated.
