2½" DACoupling
General info
The Dry Aviation Couplings are designed for use in aviation and military refuelling systems with
a maximum working pressure of 10 bar (150 psi).
This coupling is not configured for under-wing refuelling.
All units can also be used as bottom loading or primary points refuelling vehicles.
All units are manufactured to accept the international standard: 2½" the point bayonet, hose end
refuelling nozzles, according to: ISO 45 / MS24484 / STANAG 3105 /
British Aerospace Spec. 2C14.
The couplings consist of high strength Aluminium Body, Coupling ring in Gunmetal and Bayonet
flange and inner parts in Stainless Steel and Aluminium.
All wetted parts in Aluminium and Stainless Steel.
Compability Option:
ISO 45, NATO STANAG 3105, · NPT threads.
British Aerospace Spec. 2C14 · Handles.
· Sealing material; NBR etc.
Operation · Military green Nato RAL Colour.
The DACouplings include a bayonet-type
connector and are flanged or threaded to suit
installation requirements. Each Tank unit
contains a “fail safe” springloaded valve seat-
ing on a tapered seat.
The valve is controlled by the action of
coupling and uncoupling the Hose unit.

Product overview
Advantages
The Tank unit is supplied with parallel BSP threads and flat sealing surface.
This allows the use of the full thread length for screwed-on parts.
Also available with flange and tapered internal NPT threads.
PTFE (Teflon®) bearing between
the piston shaft and the piston guide
to eliminate the risk of seizure.
Inner parts in Stainless Steel
AISI 316.
Conical valve seat to eliminate the
risk for “piston blow out” when
extreme pressure is used.
Protecting ring in weather
resistant rubber.
Electrically conductive.
Coupling ring in Gunmetal to
minimize the risk of seizure.
Riveted piston pin to
minimize the risk of
failure under extreme
pressure conditions.
PTFE (Teflon®) bearings
between the driving plate
and the piston guide to
eliminate the risk of seizure.
Ball bearings in
Stainless Steel.
Shaft journal in Stainless Steel
embedded in PTFE (Teflon®) to
eliminate seizure.
The Hose unit is supplied with parallel BSP threads and flat sealing surface.
This allows the use of the full thread length for screwed-on parts.
Also available with flange and tapered internal NPT threads.
Teflon® is a registered trademark of DuPont.
