Hauff-Technik Annular Space Seal for 6 Cables D 8-35mm HRD 150-SG-6/8-35

The Hauff-Technik HRD 150-SG-6/8-35 is a high-quality annular space seal designed for sealing core drilled holes or empty pipes with a nominal diameter of DN 150. It provides gas and watertight sealing for up to 6 cables with diameters ranging from 8 to 35 mm each. The mechanical compression mechanism ensures reliable sealing, making it ideal for use in demanding environments such as telecommunications, energy, and industrial applications.

Advantages

This seal offers exceptional durability and performance. Its EPDM rubber gasket provides excellent resistance to UV radiation, chemicals, and extreme temperatures from -30°C to +100°C. The stainless steel V2A (AISI 304) hardware ensures corrosion resistance and long service life. The dry installation method simplifies setup, and the segment seal design allows for easy adaptation to various cable configurations.

Suitable for

• Sealing cable entries in building foundations, walls, and floors
• Protecting against gas and water ingress in underground installations
• Use in industrial plants, utility tunnels, and infrastructure projects
• Applications requiring a pressure rating of up to 2.5 bar
