Bought yourself a pricey pressure cleaner, outboard motor, etc and found after all that money they supplied a cheap plastic adaptor! Then flick it and replace with a solid brass adaptor. Will separate for either 3/4″ or 1″ male fittings. Or maybe you just want to take your reel from tap to tap? Then keep your system all DELRICO uniformed with this tap adaptor. ” Plastic?…no thanks!”
