RK flange connection DN200 for steel, PVC, asbestos, PN16, for water, GJS-ductile iron 21.550.200.1

Universal pipeline connection – reliability and quick installation

This RK DN200 flange-to-pipe connector is an ideal solution for both professional installers and end-users who need a quick and effective way to repair or connect a pipeline. Designed to work with various materials – steel, PVC, asbestos – and flanged fittings, it provides versatility and flexibility in many applications.

Construction and application

The connector consists of a durable body and a clamping cover made of spheroidal cast iron GJS-sfero cast iron (EN-GJS 500-7), which guarantees high resistance to pressure and mechanical damage. A conical elastomer seal ensures a tight connection. The design allows connecting pipes of different diameters in the range of DN50-DN250. This is particularly useful when repairing existing installations where access to original elements may be difficult.

• Wide application: ideal for repairing or connecting pipelines made of steel, cast iron, asbestos cement and PVC.
• Versatility: compatible with flanged fittings.
• Durability: the body and cover made of spheroidal cast iron GJS-sfero cast iron (EN-GJS 500-7) ensure long-lasting reliability.
• Tightness: the conical elastomer seal guarantees a tight connection.
• Chemical resistance: the EPDM seal provides resistance to water and certain chemicals (operating temperature 0-75°C).

Safety and compliance with standards

The RK DN200 connector has been designed with safety in mind and in compliance with applicable standards. The flanged connection meets the requirements of PN-EB 1092-2, and the materials used in production have a hygiene certificate valid until 06.2026. It can be used in water supply networks with a nominal pressure of up to 1.6 MPa. An epoxy coating RAL 5005 protects against corrosion, increasing the service life of the connector even in harsh environmental conditions.
