Greenlee 50165119 Conduit Pistons, Foam Body Fishing System Accessory

The Greenlee 50165119 Conduit Pistons are designed for use with a blower or vacuum power fishing system to pioneer the fish line through the conduit run. Featuring a flexible foam body for an air-tight seal, these pistons are built for reliable performance in conduit runs from 1/2 IN through 6 IN. A strong steel center rod with loops on both ends allows the fish line or tape to be securely attached, making these pistons a dependable choice for electricians and contractors running conduit lines on commercial and industrial jobsites. Whether pulling wire on a new-construction rough-in or fishing line through an existing raceway on a renovation project, the Greenlee 50165119 piston system gives crews a fast, repeatable way to get a pull line started through long or complex conduit runs without manual fishing.

Key Features

  • Trade Size Range: Pistons available for all types and sizes of conduit from 1/2 IN through 6 IN, covering nearly every conduit run on the job.
  • Durable Construction: Flexible foam body creates an air-tight seal inside the conduit, allowing full air pressure from the blower or vacuum system to move the piston efficiently through long or complex runs.
  • Color-Coded Identification: Color-coded end disk with embossed size markings allows for fast, easy selection of the correct piston size on the truck or in the shop, reducing downtime searching for the right part.
  • Steel Center Rod: A strong steel center rod runs through the piston body with loops on both ends, giving installers a secure attachment point for pulling line, tape, or rope through the conduit run.
  • System Compatibility: Designed to be used with a blower or vacuum power fishing system, making these pistons an essential accessory for crews running conduit fishing equipment daily.
  • Air-Tight Seal Design: The foam body's flexible construction seats securely against the conduit wall, ensuring air pressure is captured and directed to propel the piston rather than escaping around it.

Greenlee 50165119 – Frequently Asked Questions

1) What conduit sizes do the Greenlee 50165119 conduit pistons cover?
The Greenlee 50165119 piston system covers conduit runs from 1/2 inch through 6 inch trade size, and Greenlee states pistons are available for all types of conduit in that range. Each piston carries a color-coded end disk with the size embossed on it, so crews can grab the right one off the truck without measuring.
2) Do I need a blower or vacuum to use a foam conduit piston, or can I push it through by hand?
These pistons only work with a blower or vacuum power fishing system. The foam body is sized to seal against the conduit wall so air pressure (or suction) drives it through the run, carrying the fish line with it. Without a powered air source there is nothing to propel it, so if you do not own a blower/vacuum fisher, use a conventional fish tape or glow rod instead.
3) Does the piston size have to match the conduit size exactly?
Yes. The foam body has to seat against the conduit wall to make an air-tight seal, which is what captures the blower pressure and moves it along. An undersized piston lets air escape around it and stalls in the run, so pick the piston matching the trade size of the raceway you are fishing, anywhere from 1/2 inch to 6 inch. The embossed, color-coded end disk tells you which size you are holding.
4) How does the fish line attach to the Greenlee 50165119 piston?
A steel center rod runs the full length of the foam body with a loop on each end. You tie or clip your pull line, tape, or rope to a loop, and the loop on the opposite end gives you a second attachment point if you want to retrieve the piston back the other direction. The rod is steel, so the attachment point is not relying on the foam to hold the pull.
5) What are conduit pistons actually used for on an electrical rough-in?
They pioneer the pull line. Instead of pushing fish tape by hand through a long or multi-bend raceway, you drop the piston in one end, hook up the blower or vacuum, and the piston carries the line through to the far end. From there you pull in rope and then the conductors. Typical use is commercial and industrial conduit work, both new-construction rough-in and fishing an existing raceway on a renovation.
6) Where is the Greenlee 50165119 conduit piston made?
Country of origin is the United States. That matters for Buy American or domestic-preference requirements on government, institutional, and publicly funded jobs, where sourcing documentation is part of the submittal.
7) What is the Greenlee part number for these foam conduit pistons?
Order by Greenlee MPN 50165119. That is the identifier for the foam-body conduit piston with the steel center rod, covering the 1/2 inch to 6 inch conduit piston program.
