Abstract
A tire swab is provided for cleaning pipes. The swab is a tire with steel plates mounted against its sidewalls. Flexible yokes connect the plates to a cable which is used to pull the swab through the pipe. A pipe is placed through the center of the plates and the tire. The pipe allows the flow to pass through the swab while it is in use. The device can also be used as a plug for the host pipe. Compressed air is used to inflate the tire until it contacts the host pipe and plugs the flow. The pipe located in the center of the tire which allows the flow to pass is opened and closed by a valve.
