    A company called leading edge attachments makes a quick coupler called the "wedgelock". Their coupler cylinder requires 3750 PSI

    JRB makes a quick coupler.....the working pressure is the same as the bucket circiut... Komatsu calls for 2000-2500PSI.....

    Be very careful with a general question like this. Some couplers use bucket cylinder pressures and so, in the case of Komatsu this can be at least 5000 PSI...NOT 2000. Some couplers use pilot pressure and so the pressure in the cylinder will be less than 1000 PSI. Check with your specific manufacturer of the coupler

    Do you know which coupler brand it is? What machine is it on?
