Drilling band with internal thread HAKU, DN63xGW1 1/4", PN16, for water and sewage, for PE and PVC pipes, body GJS-spheroidal cast iron (series 5250) 5003583

Drilling collars – reliable connections under pressure

Drilling collars, such as the HAKU DN63xGW1 1/4" model, are key elements enabling connections of domestic installations to existing water and sewage networks without the need to disconnect the pipeline from operation. This solution is particularly useful during installation modernization or adding new water intake points. Thanks to them, it is possible to precisely make so-called "tapping" into pipes made of various materials – PE, PVC, cast iron, steel or asbestos cement.

Construction and application

The HAKU collar is characterized by a solid construction made of spheroidal cast iron (GJS), which guarantees high strength and corrosion resistance. It is equipped with a 1/4" internal thread, which ensures easy connection to the existing installation. It is designed to operate at a pressure of up to 16 bar (PN16). The special design of the collar, with precisely matched seals, ensures a leak-proof connection even when operating under pressure. This solution will be appreciated by both professional installers and end users who want to avoid interruptions in water supply during installation work.

Advantages and benefits

• Safety and reliability: Made of high-quality spheroidal cast iron and equipped with a GSK certificate confirming anti-corrosion protection, it ensures long-lasting and trouble-free operation.
• Versatility: Designed for use with PE and PVC pipes of various pressure classes (up to PN16), making it a versatile solution for different types of installations.
• Installation under pressure: Allows connections to be made without the need to shut off the water supply, minimizing disruptions in daily use.
• Easy installation: The 1/4" internal thread facilitates quick and efficient connection to the existing installation.
• Durability: Spheroidal cast iron is characterized by high resistance to mechanical damage and corrosion, which translates into a long service life of the collar.
• Compliance with standards: The product meets the requirements of European standards (EN) and ÖVGW directives or comparable national technical standards.
• Corrosion protection: The EWS coating meets the requirements of EN 14901, providing high adhesion, elongation and a smooth surface that hinders encrustation.

The HAKU collar is an investment in safe and durable connections in your water or sewage installation.
