PP reducer 400x315 SN16 (wall thickness - standard series S13.3), for external drainage, with K-U21 LOCK type gasket 0730434300

Reduction to external sewage system – reliable connection and durability

PP reduction 400x315 SN16, made of polypropylene (PP) with a wall thickness of S13.3 series, is a key element of the external sewage system. It is used to connect pipes of different diameters, ensuring a tight and durable connection. The product is equipped with a K-U21 type LOCK gasket, which guarantees easy installation and reliable operation for a long time.

Construction and application

This reduction is intended for use in external sewage systems made of PVC or PP. Its construction based on high-quality polypropylene provides resistance to corrosion, mechanical damage and weathering. The reduction allows for a smooth transition between pipes with diameters of 400 mm and 315 mm, which is particularly useful when adapting existing installations or creating new sections of the sewage network. The LOCK type gasket additionally protects the connection against leaks and ensures its long-term tightness.

Advantages and benefits

• Durability and resistance: Polypropylene is characterized by high resistance to chemicals, abrasion and temperature changes, which translates into a long service life of the reduction.
• Tightness: The K-U21 type LOCK gasket provides reliable sealing of the connection, minimizing the risk of leaks and environmental pollution.
• Easy installation: The socket connection system with a gasket facilitates and speeds up the installation of the reduction, saving time and labor costs.
• Compliance with standards: The product meets the requirements of PN-EN 1852-1 standard and has ITB-KOT-2017/0120 issue 1 approval, which confirms its high quality and safety of use.
• Versatility: Possibility of use with PVC or PP pipes increases the range of applications of the reduction.
• Load resistance: S13.3 series means appropriate ring stiffness, ensuring resistance to external loads (e.g. vehicle traffic).
• Minimization of pressure losses: Smooth transition between different pipe diameters reduces pressure losses in the flowing medium.

This reduction is a solid element of the sewage system that will work well both in new installations and in the modernization of existing networks. Its high quality of workmanship and compliance with standards guarantee trouble-free use for many years.
