Oil-resistant flexible joint VPC DN/OD330-400mm, for drainage pipes made of various materials (cast iron, PP, PE, PVC, stoneware, concrete, GRP, other smooth, corrugated, ribbed) VPC400OEL_0000

Flexible connection of various drainage materials

The Funke VPC flexible connector is a reliable solution for connecting drainage pipes made of different materials – cast iron, PP, PE, PVC, stoneware, concrete, GRP and others, both smooth, corrugated and ribbed. It allows connection of pipes with different outer diameters, eliminating the need for additional adapters in many cases. The connector design ensures a secure and tight connection, minimizing the risk of leaks and ensuring long-term functionality.

Construction and principle of operation

The connector consists of several key elements: an elastomer sealing cuff made of EPDM (according to PN-EN 681-1 WC/60), a positioning basket made of durable plastic and two steel alloy straps. The cuff has a double sealing profile for increased reliability. The positioning basket centers the connected elements, and the straps allow precise adjustment to different diameters. The straps are made of V4A stainless steel (1.4404), which ensures corrosion resistance and resistance to aggressive chemicals – including oils and gasoline. The use of this material is particularly important in environments exposed to sewage and soil.

Advantages and benefits

• Versatility: Ability to connect pipes made of different materials and with different outer diameters – without the need for additional elements.
• Tightness: The double sealing profile of the cuff guarantees reliable sealing according to PN-EN 1610 standard.
• Chemical resistance: Elements made of materials resistant to oils, gasoline and aggressive substances contained in sewage and soil – an ideal solution for difficult operating conditions.
• Easy installation: The connector design allows quick and secure installation without specialized tools (although a dedicated mounting key facilitates the work).
• Flexibility: The connector compensates for small shifts and irregularities in the installation, reducing stress and increasing the durability of the connection.
• Durability: V4A steel provides high corrosion resistance, and the solid construction guarantees long-term use.
• Safety: A secure connection minimizes the risk of leaks and failures of the drainage system.

The VPC connector is an optimal choice for both professional installers looking for a universal and reliable solution, and for end customers who value durability and safety of the drainage system.
