Is the gun also a Karcher part? If all are Karcher parts, they should fit unless the screw threads have been damaged. If they are not all Karcher parts, they will not fit because Karcher connectors are different from almost all others. Please post again if this doesn't help, giving as much detail as possible, and I'll see what else I can offer.
