3-Inch Foam Conduit Piston Pack

This Gardner Bender pack supplies five grey foam pistons sized for 3-inch conduit runs. Each piston measures 3.25 inches long and 3.3 inches wide, fitting EMT, flexible, IMC, PVC and rigid conduit types. The foam construction creates a reliable seal for pulling line through long or curved sections. Electricians running multiple jobs will appreciate the ready supply of carriers.

Compatible Blower and Vacuum Operation

The pistons work with Gardner Bender blower and vacuum units including models B60, BV208DA and JO225LC. Foam material reduces friction against conduit walls while maintaining the air pressure needed to push or pull a line. No lubrication is required and the lightweight pistons add minimal resistance during normal pulling cycles. They store flat and deploy quickly on site.

Sustained Pulling Through Long Runs

Under continuous pulling tension the foam compresses evenly to keep the seal intact over extended distances. The pack of five allows rotation between pistons if one becomes worn or contaminated on a demanding job. Performance stays consistent across EMT, flexible, IMC, PVC and rigid conduit without the pistons binding or losing pressure. Buyers needing larger diameter pistons or metal carriers will need a different product.

Questions about this item

How do I install the 3 in foam piston into EMT conduit and what step causes jams?

Push the 3.25 in piston straight into the 3 in conduit; forcing it at an angle folds the foam and blocks the line.

When will the grey foam carriers need replacement?

Replace the 5 carriers when the foam tears or compresses so it no longer seals against the conduit wall.

What limits pulling distance with the B60 blower before the piston stalls?

Friction in long 3 in runs overcomes the blower pressure and the 3.3 in wide piston stops moving.
