Universal drilling collar – reliable connection under pressure

The HAKU drilling collar with internal thread and cutting sleeve is a solution dedicated to professionals and end-users who need to make a connection to an existing water or sewage network without having to take it out of operation. It allows for precise drilling of a hole in PE or PVC pipes, ensuring a tight and durable connection. This is an ideal solution both during the installation of new connections and the repair of existing installations.

Design and application

The HAKU DN90xGW2" collar is made of high-quality spheroidal cast iron (GJS-cast iron), which guarantees strength and corrosion resistance. The insert made of ethylene-propylene-diene monomer rubber (EDPM) provides excellent tightness, even under varying pressure and temperature conditions. The collar is designed for pipes with an outer diameter of 90 mm and a nominal diameter of DN 90, and its internal thread (GW2") allows for easy connection to the installation. Thanks to its special design, the collar allows for safe drilling of pipes under pressure, minimizing the risk of damage to the installation and leaks.

Advantages and benefits

• Safety: The ability to drill pipes under pressure eliminates the need to shut down the installation, saving time and minimizing disruptions in water supply or sewage disposal.
• Versatility: Designed for PE and PVC pipes of all pressure classes up to PN16, making it compatible with most water and sewage installations.
