Greenlee 50165135 Conduit Piston, Foam Fishing System Accessory
The Greenlee 50165135 Conduit Piston is a purpose-built accessory engineered to pioneer a pull line through conduit runs when used with a blower or vacuum power fishing system. Featuring a flexible foam body that forms an air-tight seal inside the conduit, this piston is designed to work across the full range of conduit types and sizes, from 1/2" through 6". Electricians and contractors rely on Greenlee conduit pistons for fast, dependable line placement on commercial and industrial wiring projects where manual fishing is impractical or too slow. The piston's design allows it to travel efficiently through long conduit runs, eliminating the labor-intensive process of manually feeding fish tape section by section, and helping crews complete wire-pulling tasks in a fraction of the time.
Key Features
- Trade Size: Pistons are available for all types and sizes of conduit from 1/2" through 6", supporting a wide range of conduit runs and job requirements.
- Air-Tight Seal: The flexible foam body creates an air-tight seal within the conduit, allowing the piston to be efficiently propelled by a blower or vacuum power fishing system without air leakage slowing its travel.
- Color-Coded Identification: Each piston features a color-coded end disk with embossed size markings for fast, easy selection of the correct piston on the jobsite, reducing mix-ups and wasted time.
- Durable Center Rod: A strong steel center rod runs through the piston with loops on both ends, providing a secure attachment point for pull line or tape as it travels through the conduit.
- System Compatibility: Designed for use with blower or vacuum power fishing systems to pioneer the line through the conduit run, streamlining the wire-pulling process from start to finish.
- Broad Conduit Compatibility: Suitable for use across all types of conduit, making it a versatile accessory for electricians working with mixed conduit systems on a single project.
- Foam Body Construction: The flexible foam material conforms to the conduit interior, maintaining a consistent seal even through bends and offsets in the run.
