HAKU drilling band with internal thread, DN225xGW2", PN16, for water and sewage, for PE and PVC pipes, body GJS-spheroidal cast iron (series 5250) 5003764

Universal drilling collar – reliable connection under pressure

The HAKU drilling collar with internal thread DN225xGW2", PN16, is a solution designed for making connections of domestic installations to existing water and sewage networks. It allows for safe and effective creation of so-called tapping, i.e. holes in PE and PVC pipelines, without the need to disconnect them from operation. This saves time and minimizes disruptions in water supply.

Design and application

Made of durable spheroidal cast iron GJS-400-18 (series 5250), the collar ensures long-lasting and reliable operation even in difficult conditions. The special design, with a double steel tape, guarantees stable mounting on the pipe. The internal thread compliant with EN ISO 228 standard allows for easy mounting of fittings and valves. The collar is dedicated to PE and PVC pipes of all pressure classes up to PN16, making it a universal element of installations. Additionally, the set includes screws, nuts and washers made of stainless steel A2, which ensures corrosion resistance.

Advantages and benefits

• Safety: The ability to drill pipes under pressure eliminates the need to disconnect them from operation, minimizing disruptions in water or sewage supply.
• Versatility: Intended for PE and PVC pipes of various pressure classes (up to PN16) makes the collar compatible with a wide range of installations.
• Durability: Made of spheroidal cast iron GJS-400-18 ensures high resistance to mechanical damage and corrosion.
• Corrosion resistance: GSK certificate confirms the high quality of the collar's anti-corrosion protection, which extends its lifespan.
• Easy installation: Internal thread compliant with EN ISO 228 standard facilitates connection of fittings and valves.
• Tightness: The HAKU sealing system ensures a tight connection even under variable operating conditions. In the case of PE/PVC pipes, rubber gaskets cover the entire contact surface, providing optimal sealing.
• Protection against twisting: Rubber inserts glued into the bottom part (for diameters 110–315) prevent the collar from shifting during operation.

The HAKU collar is an ideal solution for both professional installers and end customers looking for a reliable way to make a water or sewage connection without unnecessary downtime.
