Minerallac 67748 Foam Conduit Piston 1-1/2 Inch

Product Description

The MINERALLAC 67748 is a foam conduit piston designed for use in electrical conduit sealing and pulling applications. This piston fits 1-1/2 inch conduit and creates a seal that allows compressed air or pulling lubricant to be applied uniformly during wire and cable installation. Electricians and low-voltage installers rely on foam conduit pistons to reduce friction, protect conductors, and speed up pulls through long or complex conduit runs. The lightweight foam construction compresses to conform to the inner wall of the conduit, maintaining consistent contact throughout the pull.

This piston is suited for residential and commercial electrical work where conductors need to be pulled through 1-1/2 inch EMT, rigid, or PVC conduit. It is commonly used in new construction, retrofit wiring, and maintenance situations where pulling through a conduit run without damaging insulation is a priority. The 67748 is a single-use consumable item that electricians typically stock alongside pulling lubricant and wire mesh grips as part of a standard pull kit.

Key Features

• Sized for 1-1/2 inch conduit for consistent fitment during wire pulls
• Foam construction conforms to conduit inner wall to maintain an effective seal
• Lightweight at 0.02 pounds, adding no meaningful load to a pull kit
• Works with compressed air or pulling lubricant to reduce conductor friction
• Consumable design intended for single-use application per pull

Compatibility

Designed as an OEM-style replacement foam piston for 1-1/2 inch conduit pulling applications in standard residential and commercial electrical installations.

Installation Notes

Installation is performed by licensed electricians in accordance with applicable NEC requirements. De-energize any circuits in the conduit run before beginning the pull. Insert the foam piston into the conduit opening ahead of the conductors, then apply compressed air or pulling lubricant as appropriate to assist the pull. Do not reuse the piston after a completed pull, as the foam may be compressed or contaminated.
