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.

Technical Specifications

  • Available Sizes: 3/4", 1-1/4", 1-1/2", 2-1/2" (piston family spans 1/2" through 6")
  • Body Material: Flexible Foam
  • Center Rod: Steel, with loops on both ends
  • Country of Origin: USA

Typical Applications

  • Starting a Conduit Run with a Power Fishing System
  • Blower-Assisted Cable and Wire Pulling
  • Vacuum-Assisted Line Placement in Conduit
  • Commercial and Industrial Conduit Installations
  • New Construction and Retrofit Conduit Runs

Why Greenlee?

Greenlee builds its conduit pistons with a strong steel center rod and a flexible foam body specifically engineered to seal tightly within the conduit while withstanding the pulling forces of blower and vacuum fishing systems. The color-coded, embossed sizing system reflects a focus on jobsite efficiency, helping electricians quickly grab the right piston for the conduit size at hand across the full 1/2" to 6" range. Manufactured in the United States, Greenlee conduit pistons are built to deliver dependable performance for professional electrical and low-voltage cable installation work.

Greenlee GREE614 – Frequently Asked Questions

1) What conduit sizes do the Greenlee foam conduit pistons come in?
Four sizes are orderable: 3/4 inch (part 609-5), 1-1/4 inch (611-3), 1-1/2 inch (612-2), and 2-1/2 inch (614). Greenlee makes the piston family for conduit trade sizes 1/2 inch through 6 inch, so if your run is 1/2, 1, 2, 3, 4 or 6 inch you need a different piston number than the four above. Match the piston to the conduit's trade size, not to the cable you're pulling.
2) Do I need a blower or vacuum to use a Greenlee conduit piston?
Yes. The 614 piston is not a push device, it's a carrier. The foam body seals against the conduit wall so air pressure from a blower, or suction from a vacuum, drives it down the run and pulls your line behind it. Without a power fishing system there's nothing to move it, and you'd be back to fish tape or rods.
3) Can I use one piston for both 1-1/4 and 1-1/2 inch conduit?
No. Pistons are sized per trade size, so 1-1/4 inch conduit takes the 611-3 and 1-1/2 inch takes the 612-2. Run the smaller piston in the larger conduit and air bypasses it, so it stalls; force a larger piston into smaller conduit and it jams. Buy one for each size you work in.
4) How do you attach fish line to a Greenlee 614 piston?
A steel center rod runs through the foam body with a loop at each end, so you tie or clip your pulling line to either loop. Dual loops mean you can shuttle the piston back the other direction without re-rigging, and the steel rod takes the tug instead of tearing out of the foam.
5) Will a conduit piston make it through bends in an existing conduit run?
The body is flexible foam, which is what lets it compress through sweeps and offsets while still holding a seal against the conduit wall. It's intended for long or bent runs under blower or vacuum pressure, in new or existing conduit, including runs that are partially obstructed. A fully blocked or badly crushed conduit still has to be cleared first.
6) Does the conduit material matter, PVC versus EMT versus rigid?
No. Greenlee states the piston family suits all types and sizes of conduit across the 1/2 inch to 6 inch range, so PVC, EMT and rigid are all fair game. What you're matching is the trade size, since the foam has to seal on the inside wall.
7) How do I tell these pistons apart once they're loose in the truck bin?
Each piston has a color-coded end disk with the trade size embossed on it, so you read the size right off the face instead of measuring or guessing. That matters if you carry several sizes, since an undersized piston loses its seal and won't travel.
8) Are Greenlee conduit pistons made in the USA?
Yes, Greenlee manufactures these conduit pistons in the United States, which is the answer government, school district and other public-works buyers need for domestic-sourcing requirements on a bid.
