## Long description

Expansion kit for the REHAU RAUTHERM SPEED HKV-P manifold with a 17 mm connector designed to extend or modify existing RAUTHERM SPEED HKV-P installations. The kit includes fittings compatible with RAUTHERM SPEED hydraulic distribution systems and is intended for use where the original manifold layout requires an additional branch or connection. It is suitable for integration into underfloor heating and radiator circuits that use RAUTHERM SPEED components and 17 mm push-fit or compression connections.
Advantages
The expansion kit offers a compact solution to add an extra circuit to an HKV-P manifold without replacing the entire manifold assembly. It is engineered to match RAUTHERM SPEED geometry and sealing standards, ensuring secure mechanical and hydraulic connections. The 17 mm connector provides a standardised interface for common piping used in heating applications, simplifying installation and reducing the need for additional adaptors.
Suitable for
Extending RAUTHERM SPEED HKV-P manifolds with an additional branch
Modifying existing underfloor heating circuits to add zones
Connecting radiator circuits to a RAUTHERM SPEED distribution manifold
Repairing or upgrading installations that use 17 mm connections
Key specifications
