Operating principle and application
DAC couplings for aviation fuel transfer
MannTek DAC couplings are intended for transfer within aviation fuel logistics, including tanker and refuelling vehicle loading and unloading. The 2½-inch interface follows ISO 45 and STANAG 3105 as specified by the manufacturer.

Configuration guidance
Is DAC approved for into-plane refuelling?
MannTek excludes DAC from into-plane refuelling and states that these couplings are not approved for underwing refuelling. Their intended application is transfer between equipment in the fuel logistics chain.
How does coupling size differ from connection size?
The 2½-inch designation identifies the interface between the tank and hose units. The pipe or hose connection has a separate specification, defined in the relevant configurator step.
