## Summary description

Expansion kit for the REHAU RAUTHERM SPEED manifold HKV-P, supplied with a 16 mm coupling. Designed to extend the functionality of the HKV-P manifold system, the kit provides compatible mechanical connection for additional circuits or components. Intended for use in hydronic heating and underfloor heating installations where the RAUTHERM SPEED manifold is deployed.

## Long description

The REHAU expansion kit for RAUTHERM SPEED manifold HKV-P with 16 mm coupling is an accessory designed to extend the RAUTHERM SPEED manifold system. It provides a compatible mechanical connection point for adding extra circuits or components to the HKV-P manifold assembly used in hydronic heating and underfloor heating systems. The kit is intended to integrate smoothly with existing RAUTHERM SPEED installations to increase capacity or adapt the manifold layout without replacing the main manifold.
Advantages
The expansion kit offers a compact and precise coupling solution sized for 16 mm piping, ensuring reliable mechanical connection and alignment with RAUTHERM SPEED components. It simplifies installation of additional circuits by providing pre-matched dimensions and compatibility with the HKV-P manifold design. The accessory reduces the need for custom fittings and helps maintain consistent hydraulic performance across connected circuits.
Suitable for
Extending RAUTHERM SPEED HKV-P manifolds with extra heating circuits
Adding distribution branches to underfloor heating systems
Modifying manifold layouts during renovation or expansion
Creating connection points for additional valves, flow meters or accessories
Key specifications
Compatibility: designed for RAUTHERM SPEED HKV-P manifold assemblies
Coupling size: 16 mm mechanical coupling for pipe connection
Application: hydronic heating and underfloor heating distribution
Mounting: intended for inline integration with HKV-P manifold ports
How to use
Install the expansion kit by shutting down the heating circuit and isolating the relevant manifold section. Remove any blanking cap or existing end fitting from the target HKV-P port and fit the expansion coupling according to RAHAU-compatible orientation. Ensure the 16 mm pipe is cut square, deburred and inserted fully into the coupling; secure according to the manifold’s mechanical connection requirements. After mechanical installation, pressure-test the extended manifold section and restore system operation following applicable commissioning procedures.
Usage recommendations
Use the expansion kit only with RAUTHERM SPEED HKV-P manifolds and 16 mm piping to preserve system compatibility and hydraulic balance. Follow manufacturer guidance for torque, sealing and pressure testing. For system changes affecting overall flow or temperature balance, adjust valves or commissioning settings to maintain even distribution across all circuits.
