I just bought a new Karcher 2100 unit which comes with metal fittings. I have a lot of accessories from my older K2 unit that have the bayonet fitting. I was wondering if there are any adapters made to connect the bayonet fitting to the newer gun. I have seen the reverse where there is a fitting to attach the new wand to go into the older gun, but have not seen anything to allow me to use my older accessories. The closest thing I could find was to buy a separate gun that supposedly would attach to the new hose but I would prefer to not have to swap out guns each time I wanted to use an accessory. The other option was to go with a K4 Premium which I picked up from Karcher but I’m not impressed with the construction and feel of the K4 compared to the 2000. The only reason for keeping the K4 would be that I don’t have to go buy all the accessories I already own.
My guess is you’ll have to put a call into Karcher. I don’t think anyone here is familiar with these smaller pressure washing units. Good luck. 
Went right over my head lol
Post some pictures.
Photo shows Karcher old handle that accepts bayonet accessories, new handle with metal fitting, 2 older accessories with bayonet, and an adapter sold that allows you to use the older bayonet handle with new metal fittings to newer type accessories. I’m looking for the reverse - to adapt the older bayonet accessories to the newer metal handle.
That looks like it might work. Can’t be 100% sure from the photo angle or description but I’m going to take a chance and order it. If it turns out not to be what I need it’s an easy return to Walmart. Thanks for the suggestion.
