Short DescriptionDAC
Self locking quick connect/disconnect coupling for aviation fuel, to ISO 45, MS24484 and STANAG 3105 - with 2½" bayonet connection.
DescriptionHose unit with swivel, typically mounted on hose assemblies and loading arms for temporary connection between storage tank and mobile transport unit for loading and unloading.
Tank unit without swivel, typically fix mounted as a filling connector on storage tanks, aviation refuellers and mobile tank containers.
CommentQuick and safe connection of hose assemblies and loading arms to mobile and stationary tanks, under pressure and with minimised liquid loss.
DAC couplings are suitable e.g. for bottom loading of aviation refuellers. They are not certified for underwing refuelling. All wetted parts of the coupling are free from yellow metal such as brass/bronze, safeguarding media purity.
Both coupling parts are equipped with a flat poppet valve. For the connection, the hose unit is pushed onto the tank unit and coupled / sealed by turning the coupler clockwise by 15 degrees. When the unit is turned by 100 degrees, the valves move into the tank unit so that the medium can flow. When a similar turn is made counter-clockwise, the flow is stopped and the coupler can be pulled off.
Sizes2½" (coupler diameter Ø 105 mm).
ConnectionsBSP/NPT thread, DIN/ANSI/TW/TTMA flange – others on request.
PressureCan be coupled up to 10 bar line pressure.
Working pressure PN 10.
Temperature-20° C up to +55° C; (low temperature version down to -55° C available).
MaterialBody: aluminium
O-Rings: Viton® (FPM/FKM) – others on request.
Flat seal (for female parallel thread connections only): polyurethane – others on request.
Approvals / CertificatesDAC couplings fulfill the requirements of European Pressure Equipment Directive category 2.
They are suitable for the use in potentially explosive atmosphere (ATEX) zone 1, approved for the transport of dangerous goods on road (ADR) and by rail (RID).
