Minerallac 67756 Foam Conduit Piston

Minerallac 67756 3-1/2" Foam Conduit Piston

The Minerallac 67756 is a 3-1/2" foam conduit piston designed to help electrical contractors prepare conduit runs before pulling wire or cable. Built from lightweight, flexible foam, this piston-style swab is sized to match 3-1/2" conduit and is intended to travel the length of the raceway, helping to clear loose debris, dust, and moisture that can collect inside conduit during and after installation. Foam conduit pistons like the 67756 are a familiar sight on electrical jobsites, where clean, dry raceways help crews avoid snags, damaged insulation, and delays once it's time to pull conductors. As a purpose-built conduit accessory from Minerallac, the 67756 is a practical addition to any electrician's conduit-prep kit, supporting cleaner, more efficient cable pulls on commercial, industrial, and residential jobsites.

Key Features

• Trade Size: Sized at 3-1/2" to correspond with matching conduit runs, helping ensure full contact with the raceway wall as the piston travels its length.
• Foam Construction: Lightweight, flexible foam body is designed to conform to the interior wall of the conduit, helping to dislodge and carry out debris, dust, and moisture ahead of a wire or cable pull.
