Gasket for Diamir corrugated pipes 400K

This external gasket, designed for corrugated pipes with a diameter of 400 mm, is a key element of Diamir drainage systems. It ensures a tight connection in manholes, both for single- and double-layer pipes. It is indispensable during the construction of gravity sewer networks – sanitary, rainwater, combined, industrial, and drainage systems.

Application and compatibility

The 400K gasket is widely used in complete Diamir manholes. It is dedicated to:

• Kinety (pipe connecting elements)
• Manset 400K (sealing connections)
• Bottom covers (ensuring tightness at the contact with the base of the manhole)
• Non-access and access manholes – where a tight connection of system elements is required.
• Manholes with a sediment trap – ensuring proper functioning in drainage and rainwater drainage systems.

Thanks to its versatility, it works well both in new installations and during the modernization of existing sewer networks.

Construction and product features

The gasket is made of materials resistant to sewage and weather conditions. Its construction guarantees a durable and reliable seal, minimizing the risk of leaks and groundwater infiltration. The use of this gasket translates into long-term and trouble-free operation of the entire drainage system. Its dimensions (400 x 400 x 28 mm) have been precisely matched to the standard elements of Diamir 400K manholes, which facilitates installation and ensures optimal tightness. The black color of the gasket helps in its identification during installation work.
