I recently acquired a Kostiner 11x14 archival washer, which the seller had thrown out the old hose that supplied the washer with water. They also threw out the adapter that allowed the hose to firmly connect to the washer. Does anyone know what is the correct size adapter for it? Is it metric and not imperial? I've tried 3/8" and that's too loose, and 1/2" and that's too big.
