Greenlee 50110381 Conduit Piston, Flexible Foam Fishing Tool

The Greenlee 50110381 Conduit Piston is a flexible foam fishing tool built for use with a blower or vacuum power fishing system, letting electricians pioneer a fish line through a conduit run quickly and efficiently. Its flexible foam body forms an air-tight seal inside the conduit, which is essential for generating the pressure differential that a blower or vacuum system relies on to propel the piston through the raceway. Pistons in this family are available for all types and sizes of conduit, from 1/2 IN through 6 IN, making this a versatile solution for nearly any conduit run encountered on the jobsite. A color-coded end disk with embossed size markings speeds up selection on the truck or in the gang box, so crews can grab the correct piston size without guesswork or wasted time.

Key Features

  • Trade Size Range: Pistons are available for all types and sizes of conduit from 1/2 IN through 6 IN, covering nearly every conduit run on a job.
  • Durable Construction: A flexible foam body forms an air-tight seal against the conduit wall, letting a blower or vacuum system build the pressure needed to drive the piston through the run.
  • Color-Coded Identification: A color-coded end disk with embossed size markings allows for fast, easy size selection in the field, reducing time spent sorting through mixed piston inventory.
  • Steel Center Rod: A strong steel center rod runs through the piston with loops on both ends, giving installers a secure attachment point for fish tape, rope, or pull line.
  • System Compatibility: Designed to work with blower or vacuum power fishing systems, the piston is pulled or blown through empty conduit to establish the initial pull line before conductors are installed.
  • Time Savings: By pioneering the fish line through the conduit pneumatically, the piston eliminates much of the manual fishing labor typically required on long or congested conduit runs.

Why Greenlee?

Greenlee builds its conduit pistons with a flexible foam body designed to hold an air-tight seal and a strong steel center rod with loops on both ends for a dependable pull-line connection. The color-coded, embossed end disks make it easy for crews to select the right piston size quickly, helping keep pneumatic fishing operations moving efficiently across jobsites of every scale. For electrical contractors who rely on blower and vacuum fishing systems, Greenlee's conduit pistons deliver the consistent, air-tight performance needed to pioneer lines through conduit runs from 1/2 IN through 6 IN, whether on a small tenant build-out or a large industrial installation with dozens of long, congested raceways to fish.

Greenlee 50110381 – Frequently Asked Questions

1) What is a Greenlee conduit piston used for on a wire pull?
A conduit piston is the first thing through an empty raceway. The Greenlee 50110381 is a flexible foam piston that a blower or vacuum power fishing system drives down the conduit, carrying a fish line with it. Once that line is in, you use it to pull rope and then conductors. It replaces most of the hand fishing on long or congested runs.
2) Do I need a blower or vacuum to use the Greenlee 50110381 piston, or can I push it through by hand?
It needs air. The foam body is sized to form an air-tight seal against the conduit wall, and that seal is what lets a blower or vacuum build the pressure differential that moves the piston down the run. Without a power fishing system there is nothing to propel it.
3) What conduit sizes do Greenlee conduit pistons cover?
Greenlee makes pistons for all types and sizes of conduit from 1/2 inch through 6 inch trade size. Each piston is sized to one conduit size, since the seal depends on a close fit, so match the piston to the raceway you are fishing rather than expecting one to cover a range.
4) How does the fish line attach to the Greenlee 50110381 piston?
A steel center rod runs the length of the foam body with a loop on each end. You tie or clip your fish line, mule tape, or pull rope to a loop. Loops on both ends mean you can hitch a line at the trailing end and still have an attachment point at the nose if you need to pull it back out.
5) Can I use this piston in PVC as well as EMT and rigid conduit?
Yes. Greenlee states these pistons are made for all types of conduit in the 1/2 inch to 6 inch range, so the limiting factor is the trade size and the condition of the raceway, not the conduit material.
6) How do I tell piston sizes apart in a gang box full of them?
Each Greenlee conduit piston has a color-coded end disk with the size embossed on it. On the truck or in a mixed bin you pick by color and confirm by the stamped size, which is the point of the design.
7) Where is the Greenlee 50110381 conduit piston made?
Country of origin is the United States. That matters on public and federally funded jobs where domestic sourcing is part of the procurement spec.
8) What is the manufacturer part number for this Greenlee conduit piston?
Order it as Greenlee 50110381. That is the manufacturer part number for the flexible foam conduit piston with the steel center rod.
