Kraso - Blank / Empty Mechanical Duct Sealing System

by Kraso
Description

The Kraso Blank Mechanical Duct Seal, also known as the Blind Duct Seal or Empty Duct Seal, is engineered to seal empty ducts containing no cables or pipes, offering a versatile and reusable option for your network. When the duct is required for use, the seal can be easily removed and applied elsewhere in the network to secure another empty duct, providing flexibility and efficiency.

Choose from three levels of pressure resistance to meet your specific needs:

  • Kraso Type ED: Offers up to 1.0 bar protection against water and gas.
  • Kraso Type DD: Delivers up to 3.0 bar of protection, ideal for more challenging environments.
  • Kraso Type VD: Provides exceptional protection with up to 8.0 bar of resistance, designed for the most demanding conditions.

The Kraso ED, DD, & VD Blank Duct seal system is more than just a duct seal; it's a comprehensive solution that excels in even the harshest conditions. Like all Kraso duct sealing products, it is meticulously designed to prevent flooding, gas infiltration, moisture ingress, and rodent entry. The seal consists of two elements, ensuring easy installation, even in wet or water-prone areas.

Crafted from high-grade V2A stainless steel, this duct seal is corrosion-resistant and built to last, making it a reliable choice for long-term protection. The Kraso ED seal also features Kraso's patented Torque Control Nut, a unique innovation that simplifies installation by ensuring precise tension without the need for a torque wrench. This design ensures the seal is neither under-tightened nor over-tightened, providing peace of mind and superior performance.

Key Features:

  • Pressure Resistance: Up to 1.0, 3.0, or 8.0 bar, depending on the selected type.
  • Patented Torque Nut: No torque wrench is required for installation.
  • Gas Resistance: Effective against toxic gases such as Radon, Hydrogen Sulphide, Methane, and Chlorine.
  • Hydrocarbon Resistance: Safeguards against harmful hydrocarbons.
