Ball joint PP DN 315/0-7.5 degrees SN16 (wall thickness group S13.3), for external sewage systems, with K-U21 LOCK type gasket 0718293310

External drainage ball joint – durable and flexible connections

The ball joint, made of polypropylene (PP), is an indispensable element of the external drainage system. It is used to connect pipes with a diameter of 315 mm, allowing compensation for small angular deviations of up to 7.5 degrees. This makes the installation more flexible and resistant to stress, which translates into its long-term reliability. Designed for use with PVC or PP pipes, it provides a tight and durable connection thanks to the use of a K-U21 type LOCK gasket.

Design and application

The ball joint from the SN16 series with a wall thickness of S13.3 is characterized by high circumferential rigidity, which guarantees the stability and durability of the entire installation. This is particularly important in places exposed to external loads, such as vehicle traffic or ground changes. The use of a ball joint allows for precise adaptation of drainage elements to terrain conditions, minimizing the risk of damage and leaks. A key element is the K-U21 type LOCK gasket used, which ensures a reliable seal of the connection, preventing sewage from entering the ground.

Advantages and benefits

• Flexibility: Compensation for angular deviations of up to 7.5 degrees facilitates installation in difficult terrain conditions and reduces stress in the installation.
• Durability: Made of high-quality polypropylene (PP) and SN16 stiffness ensure resistance to corrosion, abrasion and mechanical damage.
• Tightness: The K-U21 type LOCK gasket guarantees a reliable seal of the connection, eliminating the risk of leaks and environmental pollution.
• Compatibility: Designed to connect PVC and PP pipes, which increases the possibilities of use in various drainage systems.
• Easy installation: The socket connection system with a gasket facilitates and speeds up the installation process, reducing labor costs.
• Compliance with standards: The product meets the requirements of PN-EN 1852-1 standards and has technical approvals ITB AT-15-7558/2016 and IBDiM KOT-2018/0270, which confirms its high quality and safety of use.
