Dry Aviation Couplings
Designed in accordance with global standards ISO 45 and STANAG 3105 for the handling of aviation fuel, Dry Aviation Couplings (DAC) can be used at almost any transfer point within the fuel logistic chain.
Dry Aviation Couplings feature integrated valves and are operated via a turning motion to connect or disconnect, automatically opening and closing flow paths in one motion with minimal product loss.
Applications include the loading and unloading of tank trucks and aviation refuellers, de-fuelling, and defence applications. Please note: these couplings are not for into-plane refuelling.
