Conduit pistons are used with blower or vacuum power fishing systems to
pioneer the line through the conduit run. Their flexible foam body forms
an air tight seal against the interior of the conduit. End disks are
color coded with embossed size markings to help the user easily identify
the correct size piston. The center rod is made of durable steel and
has loops on either end. Conduit rats are available for all types and
sizes of conduit - 1/2" through 6".
