Band with internal thread HAKU, DN225xGW1 1/4", PN16, for water and sewerage, for PE and PVC pipes, housing made of ductile cast iron (series 5250) 5003758

Universal Clamp for Live Drilling – Reliable Pressure-Tight Connection

The HAKU drilling clamp, manufactured from ductile iron GJS-400-18, is specifically designed for creating pressure-tight connections to PE and PVC pipes. It enables safe and efficient creation of so-called “taps” – holes drilled into existing pipelines – without the need to shut down the system. This is an ideal solution for both professional installers and end-users requiring a reliable method to connect new water or sewer line connections.

Design and Application

The HAKU clamp, featuring an internal thread of 1 1/4 inch (GW1 1/4") and nominal diameter DN225, is rated for operation at PN16 pressure. Constructed from high-quality ductile iron, it ensures durability and corrosion resistance. The sealing system, based on rubber inserts, guarantees leak-tight performance, especially critical when connecting plastic pipes. Live drilling capability significantly reduces installation time and minimizes disruptions to water supply. This clamp is suitable for both municipal water and sewer systems, applicable in residential and industrial installations.

Features and Benefits

• Safety: Drilling under pressure eliminates the need to drain or shut down pipelines, enhancing safety and user comfort.
• Durability: Ductile iron construction provides excellent corrosion resistance and long-term reliability.
• Leak-tightness: Special sealing system ensures tight connections even under varying operating conditions.
• Versatility: Compatible with PE and PVC pipes of various pressure classes (up to PN16), expanding application range.
• GSK Certification: Confirms anti-corrosion protection, extending product lifespan and minimizing failure risk.
• Easy Installation: Clamp design simplifies mounting and disassembly, saving time and labor costs.
• Standards Compliance: Meets requirements of EN ISO 228 and EN 1092-2 (PN16), ensuring safety and quality.
• Hole Size: Enables drilling of holes up to 40 mm in diameter (depending on pipe diameter).

The HAKU clamp is an investment in a reliable, long-lasting solution that ensures safe and efficient connection of water or sewer line connections.
