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.
