A tube flushing device has a shell having a first housing and a second
housing connected on a side thereof so as to be movable between an open
position and a closed position. A first pair of wheels are rotatably
mounted in the first housing. A second pair of wheels rotatably mounted
in the second housing. The first pair of wheels engages the second pair
of wheels when the housings are in the closed position. The shell has
openings on opposite ends thereof. A tube can extend through the openings
and between the first and second pair of wheels so as to allow fluids
therein to be flushed therefrom as the shell moves along the length of
the tube.
