      Will this fit with the replacement hose kit (HK 7.5) which comes with a 'quick connect' adaptor ?

      I have a K3.99M pressure washer and purchased the replacement hose kit but can't fit the adaptor to my pressure washer - it feels like they have different threads. The thread on the outlet cover looks worn but I'm not sure if this damage has been caused by my efforts to fit the adaptor. On the box it states that the kit is suitable for K2 - K7.
