Plastic Blank EXPANDABLE BLANK DUCT PLUGS DT40/31

Physical & Dimensional Specifications • Nominal Duct Size Compatibility: Fits ducts with a 40 mm Outside Diameter (OD). • Minimum Duct Expansion Range (ID): Formulated for an internal diameter range of 31.0 mm to 36.0 mm. • Body Construction Material: Injection-molded, high-impact Polyoxymethylene (POM) or Acrylonitrile Butadiene Styrene (ABS) engineering plastics. • Compression Plate Nut Style: Available primarily in Wing Nut (low profile for tight spaces) or Loop/Eyelet Nut configurations. • Sealing Gasket Element: Segmented, expandable Thermoplastic Elastomer (TPE) or Nitril-Butadiene Rubber (NBR) ring. Performance & Environmental Ratings • Pressure Retention: Holds an airtight operational sealing pressure up to 15.0 bar (approx. 217 PSI). • Burst Pressure Limit: Rated at >45.0 bar (>652 PSI) structural load before structural compromise. • Thermal Endurance: Designed to function under underground temperatures ranging from -15°C to +45°C. • Infiltration Security: Certified fully water-tight and gas-tight, stopping the flow of water, mud, slurry, and dangerous vapor migration. • Corrosion Resistance: Complete all-plastic and rubber design guarantees resistance against acids, oils, and chemical compositions found in municipal soil banks. Mechanical Features • Integrated Rope-Tie Anchor: Features an internal tie ring molded into the back compression plate. This holds pull-ropes or line-tapes up to 1/2-inch (12.7 mm) thick inside the dark conduit path for future splicing access. • Removable & Reusable: The compression assembly un-threads quickly without tearing up or scoring the inside walls of the HDPE pipe.
