¼ inch is correct. My brass connector arrived today but I’m waiting for a tiny pair of hands to walk in the door before I attempt to fit it. The access is too small for my big mitts.
Also, i just noticed that the original blue connector looks far more solid than the ones in photos that have failed (from other machines). So now I’m wondering if it’s even worthwhile to swap it out for brass. I may just keep the brass one as a back up.
