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. 1) 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. 2) 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.
