Greenlee 615 – Frequently Asked Questions

1) Will the Greenlee 615 foam piston work in 3 inch EMT, or only IMC and rigid?
The Greenlee 615 is sized for 3 inch IMC and rigid conduit. EMT of the same trade size has a different inside diameter, so the foam body will not seal the same way. If you're fishing 3 inch EMT, use the piston built for EMT rather than this one - the seal is what makes a blower or vacuum system pull the line, and a loose piston just stalls in the run.
2) Do I need anything besides the piston to fish a conduit run?
Yes. The 615 piston is the carrier only. You supply the blower or vacuum power fishing unit, the pioneer line or fish twine that ties to the steel rod loop, and the pull rope and cable grip for the actual cable pull. The piston does no work on its own - it exists to get that first light line through the run.
3) How does a foam conduit piston actually pull a line through conduit?
It's the carrier, not the puller. You drop the piston into one end of the run, connect a blower or vacuum unit, and air pressure drives it through while it tows a light pioneer line behind it. The foam body seals against the conduit wall so the air pushes the piston instead of slipping past it. Once the pioneer line is through, you use it to pull the heavier rope, then the cable. Greenlee's 615 has a steel center rod with loops at both ends, so you can tie off on either end depending on which way you're fishing.
4) What is the Greenlee part number for the 3 inch conduit piston?
Model 615. That's the number stamped on the order, and the piston itself carries a color-coded end disk with the size embossed on it, so when you're carrying a set of several sizes on a job you can pick the 3 inch out of the bag without measuring.
5) Can I use one piston for several conduit sizes on the same job?
No. Each piston is sized to one trade size, and the 615 covers 3 inch. The seal against the conduit wall is what makes the system work, so an undersized piston blows past the air and an oversized one binds. Contractors running mixed sizes on a building typically carry a set, one piston per trade size, and use the embossed color-coded disk to grab the right one.
6) Is a foam piston reusable, or is it a one-shot item?
It's reusable. The 615 is built around a steel center rod rather than disposable construction, with a flexible foam body around it, and it's intended for repeat use across commercial, industrial, and retrofit conduit work. Foam does wear against the inside of rigid conduit over time, so inspect the body for tears or crushed edges before each run - once it stops sealing, it stops pulling.
