Dry Break Fittings
Dry break fittings or connectors are useful in our radio control fuel systems to prevent fuel loss and avoid contamination. They are also designed to minimize the possibility of air entering the fuel system and, in turn, prevent flameouts due to an air bubble.
How do dry break couplings work?
Dry break fittings are called a ‘coupling’ because they are comprised of two separate parts – a dry break male nozzle and a dry break female receiver – that lock together to form a completely sealed conduit for the secure, cost-effective, clean, and efficient transfer of fuels and other fluids.
The dry break fittings contain internal mechanical valves that remain closed until the mating halves are fully connected, at which point an optimal fluid pathway is opened.
Once filling has been completed – either by the operator or via an automatic shut-off feature – the valves are closed and the fluid pathway completely sealed before the mating halves are uncoupled, minimizing leaks and spills. This is where the ‘dry’ part of the dry break fitting’s name comes from.
The dry break coupler separates into two fluid-tight components.
