    Pressure washer fittings - adapting a karcher

    So I`ve got this Karcher electric pressure washer (K5 something something something) that works fine for what I use it for but I`d like to be able to use some other accessories with it now and again (like gutter cleaners etc)
    So anyway, I need to adapt the karcher bayonet mount just after the trigger handle to something "normal" like the gas ones have but when I look online I see a bunch of different "standard" quick disconnects.
    What would your guess be for the most universal fitting be???

    my options for karcher to ??? seem to be

    Plastic, Thread-- G1/4 Male;
    Plastic + Solid Brass, Thread-- G1/4 Male;
    Solid Brass, Thread-- G1/4 Male;
    Plastic + Solid Brass, Thread-- G1/4 Female;
    Solid Brass[B], Thread-- G1/4 Female;



    My first thought is all brass but in the back of the mind somewhere I`m thinking the plastic would likely have a higher chance of sealing with the karcher so plastic with the solid brass male or female npt thread (option B or D in the picture)

    Then I can go to a 1/4 or 3/8 quick disconnect type thing

    Does that make sense or ???

    I have the D with a short stainless steel pipe 1/4 and threaded on both ends. Then mount the Kärcher K fitting D on one end and the other end a quick disconnect female/ female 1/4. The stainless steel pipe you can often get where they sell accessories and fittings and such. But Kärcher has a lot of products to use with their PW. They can be a little pricey but think it`s a good quality of those I have used so far.

    I have tested the brass ones and they are not so easy to mount in the wand. So only useing the plastic covered ones.

    Any reason a "B" style with the other fitting on the end and skip the stainless pipe?
