When running a mutual aid water supply operation, the probability of needing hose appliances and adaptors is pretty high - especially if departments use/carry different size suction and supply hose. During the 2-hr water supply drill at our seminar in Broken Bow, Oklahoma (March 2013), the dump site pumper crew needed some way of connecting 5-inch suction hose to 6-inch suction hose so that they could set up a water transfer system to "jump" a dump tank.

No one had a simple 5"x6" NH adaptor so the folks had to be a bit creative. Fortunately, several of the pumpers involved in the drill carried 5-inch LDH and those pumpers had adaptors to fit their pump's suction inlets. (Some pumpers had 5-inch steamers; some had 6-inch steamers.) The "fix" was simple, use 5-inch Storz adaptors: not pretty, but functional.
