Abstract: A fire truck water connection cap, which has an insert installed on the outside that displays a variety of different artwork forms. It is customizable for the individual fire department. The means of retention allows for the “upright” placement of the insert regardless of orientation of the cap when it is tight to the pump inlet. The use of an elastomeric spring presses the insert against a retention ring which holds it in place after it is rotated to the correct position. The cap also uses grips on the ends of the handles to resist a firefighter's hands or a soft mallet from slipping off the end.
