BI adapter DN225 + VPC 220 connector for connecting pipes with non-circular external geometry, oil-resistant version BIA250220OEL_0000

Adapter for non-circular pipes – leak-proof connection

This adapter, together with the VPC 220 coupling, is a solution dedicated to connecting drainage pipes with different external geometries. The construction based on an internal stainless steel sleeve, an EPDM cuff, and an expansion wedge guarantees the tightness and durability of the connection. The BI DN225 adapter is particularly useful in situations where standard connection methods fail, e.g., with concrete pipes with a foot or irregular shapes.

Construction and principle of operation

The adapter consists of several key elements that work together to ensure a safe and durable connection:

• Internal stainless steel sleeve: Provides strength and corrosion resistance. After being inserted into the pipe, the sleeve expands to fit its inner surface.
• Sealing EPDM cuff: The flexible EPDM material creates a sealing barrier between the sleeve and the pipe wall, preventing leaks.
• Stainless steel expansion wedge: Enables precise and even expansion of the sleeve inside the pipe, ensuring a strong and tight connection.
• VPC® flexible coupling: The VPC® coupling included in the set allows for a flexible connection of the adapter to the next element of the installation, compensating for small displacements and stresses. The VPC® coupling is compatible with a wide range of pipe materials (cast iron, PP, PE, PVC, stoneware, concrete, GRP).

Advantages and applications

The BI DN225 adapter + VPC 220 coupling is an ideal solution for both professional installers and end-users:

• Versatility: Suitable for all commonly used drainage pipe materials.
• Quick installation: Simple construction and intuitive installation method allow for quick and efficient connection.
• Tightness: Several annularly embedded sealing ribs guarantee a completely tight connection.
• Chemical resistance: The oil-resistant version provides resistance to hydrocarbon substances. Additionally, the adapter is acid-resistant.
• Durability: The use of high-quality stainless steel and EPDM material ensures long-term operation without the need for frequent replacement.
• Connecting pipes with irregular shapes: Specifically designed for connecting pipes with non-circular external geometries – where traditional methods fail.
• Patented solution: Product protected by a patent – a guarantee of innovation and high-quality workmanship.

This adapter is a reliable solution for demanding drainage installations, providing safety and peace of mind for years to come.
