The stem includes a head, a tail, and a shaft extending between the head and the tail. The dynamic portion is disposed around the stem. The dynamic portion is longitudinally movable along the stem between a closed position and an opened position. The dynamic portion includes a neck and a body extending longitudinally from the neck, the neck to seal around the head in the closed position and fluidly open in the opened position, the body to slidably fluidly seal against a housing between opened and closed positions. A liquid ink pathway and an air pathway are formed between the static portion and the dynamic portion.
