PP tee 315x250/87.5 SN16 (wall thickness - series S13.3), for external drainage, with K-U21 LOCK type gasket 0720294390

External drainage tee – reliable connection and durability

This PP tee with a diameter of 315x250/87.5, made of polypropylene (PP) with a wall thickness of S13.3 series, is a key element of an external drainage system. Designed to connect PVC or PP pipes, it ensures a tight and durable connection thanks to the use of a K-U21 type LOCK gasket. It is an essential element both during the construction of new installations and during the modernization of existing ones.

Design and application

This tee is used to branch pipelines in an external drainage system. Its design, based on PP material and a LOCK gasket, guarantees resistance to corrosion, abrasion and the action of chemical substances present in wastewater. It is particularly useful in places where a connection of pipes with different diameters or at different angles is required. The use of the K-U21 gasket eliminates the risk of leaks and ensures a long-lasting tight connection.

Advantages and benefits for professionals and users

• Easy installation: The spigot connection system with a LOCK gasket significantly speeds up the installation process, minimizing working time and labor costs.
• High tightness: The K-U21 gasket provides reliable sealing, preventing leaks and groundwater infiltration into the drainage system.
• Durability and resistance: Polypropylene (PP) is characterized by high resistance to atmospheric factors, chemical substances and mechanical damage, which guarantees a long service life of the tee.
• Versatility: Compatible with pipes made of PVC or PP – provides flexibility in the choice of installation materials.
• Safety: Compliance with standards for drainage systems ensures safe use and minimizes the risk of failure.
• Load resistance: Stiffness class SN16 means that the tee can withstand significant external loads, such as vehicle traffic or ground load.
• Simple disassembly: If necessary, the tee can be easily disassembled without damaging the pipeline – this facilitates service and repairs.

Thanks to these features, this tee is an optimal solution both for professional installers looking for reliable and easy-to-install elements of the drainage system, and for end users expecting durability and safety of their installation.
