Connect any hose, tap or pressure-washer thread to any other
Garden taps, hoses, pressure washers and kitchen aerators use a handful of incompatible thread standards. Pick the two ends you are trying to join and get the exact adapter, the sealing method that stops it leaking, and the traps that catch people out.
