Greenlee 614 Conduit Piston, Foam Body with Steel Center Rod
The Greenlee 614 Conduit Piston is engineered to pioneer fish line through a conduit run when paired with a blower or vacuum power fishing system. Built around a flexible foam body that forms an air-tight seal inside the conduit and a strong steel center rod with loops on both ends for secure line attachment, this piston family is available for all types and sizes of conduit from 1/2" up through 6", including the 3/4", 1-1/4", 1-1/2", and 2-1/2" sizes commonly stocked on the truck. A color-coded end disk with an embossed size marking makes fast, accurate selection simple on the jobsite, so crews spend less time digging through a bin and more time pulling wire.
Key Features
- Trade Size Range: Pistons are available for all types and sizes of conduit from 1/2" through 6", with this listing covering the 3/4", 1-1/4", 1-1/2", and 2-1/2" sizes, so electricians can match the piston to the exact conduit run.
- Durable Construction: A strong steel center rod with loops on both ends provides a reliable attachment point for fish tape or pulling line during the power fishing process, standing up to repeated tugging without pulling free.
- Air-Tight Seal: The flexible foam body conforms to the interior wall of the conduit to create an air-tight seal, allowing the piston to travel efficiently under blower or vacuum pressure across long or bent conduit runs.
- Fast Size Identification: A color-coded end disk with an embossed size marking lets electricians quickly grab the correct piston for the conduit size in use, cutting down on setup time on the jobsite.
- System Compatibility: Purpose-built for use with a blower or vacuum power fishing system to pioneer the pulling line through a new or existing conduit run, whether the conduit is empty or partially obstructed.
