Transforming Core Drills or Sleeve Pipes into Flexible Building Entries with Annular Seals

Core drilling is frequently utilized when retrofitting building entries. In such cases, practical and effective sealing solutions for the created holes and the supply lines introduced are necessary. The same applies when utilizing sleeve pipes. Hauff-Technik’s press seals are the ideal solution for these situations, ensuring a durable and leak-proof seal that meets industry standards.

Diverse Product Range – Press seals from Hauff-Technik

Hauff-Technik offers innovative solutions for core drillings and sleeve pipes, available in diameters from 50 mm to 200 mm. The press seals support a diverse range of supply lines, with larger models serving as KG pipe seals and smaller options designed for electrical and telecommunication cable installations into buildings.

The standard press seal for house connections is engineered for core drillings with a diameter of 100 mm, enabling up to five connections for various lines. Hauff-Technik employs segment ring technology in their annular seals, facilitating on-site adjustments tailored to the specific diameter of the lines. Standard connections are compatible with lines measuring 7 mm to 12 mm in diameter.

For sealing pipes, larger gaps can be efficiently addressed with link chain seals. This method is particularly effective for KG pipe seals and can be applied to any diameter or type of pipe due to its flexible design. Link chain seals also ensure gas-tight and water-tight connections for houses. The sealing process between core drillings and press seals involves a rubber compression seal.

Our seals featuring segment ring technology are designed with split seals, allowing for post-installation adjustments. This setup can safely accommodate up to ten supply lines routed through a single core drilling into the building. It supports both small lines with a 4 mm diameter and larger supply lines with up to 110 mm cross-sections.

Additionally, blind seals are part of the press seal category, allowing for the quick and secure closure of sleeve pipes or core drillings. These seals cater to openings and pipes with diameters from 20 mm to 107.5 mm and can be installed without tools, requiring only two hand movements. A sealing flange provides pressure closure, ensuring that unused core drillings or sleeve pipes are sealed gas-tight and water-tight. These can be repurposed later for various supply lines.
