DuctSeal Plug – Mechanical Sealing for Blank Ducts and Core Holes
Duct Plug – Expandable Rubber Expansion Plug & Pipe Stoppers
The DuctSeal Plug range from AC Cable Solutions is a rubber expansion plug and pipe stopper designed for rapid fitting and easy tool-free installation. Manufactured from corrosion-resistant HDPE and thermoplastic elastomer materials, these plugs form an effective seal to prevent water ingress, air leaks, dirt, and rodents—causing no mess, resin, or extra equipment on site.
Key Features
