Please see the two attached photos of the hose connector on my power washer.

I can't seem to find a model # or brand on the power washer so don't know what size connection the hose has.

I want to buy an under-carriage washer to attach to my power washer so I can clean the underside of my vehicles.
Will the connectors fit? I don't know much about this stuff. Ask me electrical and I can help you.

This is what I want to buy ---> Twinkle Star 16 Inch Dual-Function Undercarriage Cleaner, Surface Cleaner for Pressure Washer, Underbody Car Wash Water Broom with 2 Piece Extension Wand and 90 Degree Angled Wand, 4000 PSI : Patio, Lawn & Garden

I believe it should be a 1/4" connection and that this unit will fit.

Thanks for your help.

Snoonyb - sorry, I am confused with your reply.

Are you saying that I need adaptors (which you listed) in order for my hose connector to connect to the undercarriage washer I listed?
No, I was just showing you the variety I've used.

You can order the couplings from most hardw outlets.

There are also universal, which will fit both styles, of a specific size.
