A fluid coupler arrangement for a first pressurized fluid circuit is disclosed. The fluid coupler arrangement has an extendable fluid coupler. The fluid coupler arrangement also has a receiving fluid coupler, to be coupled to the extendable coupler, so that in a coupled condition of the couplers the first pressurized fluid circuit extends through the couplers. The fluid coupler arrangement also has fluid channels that extend through the couplers. The extendable coupler has a static portion and a piston that is extendable with respect to the static portion. The extendable coupler has a compensatory surface being fixedly connected to the static portion. The compensatory surface has a deviation with respect to the wall of the fluid channel of the extendable coupler, to at least partially retain the piston in an extended position when fluid flows through the couplers.
