## Long description

This brass transition fitting by REHAU, designed for RAUTITAN LX systems, connects a 25 mm polymer pipe to an R 1/2" external threaded component. It provides a metal-to-thread interface suited for plumbing and heating applications where a reliable connection between a polymer pipe and threaded valves, radiators, boilers or adapters is required. The fitting is sized and shaped for easy integration into RAUTITAN LX installations and supports both hot and cold water lines when used according to installation standards.
Advantages
The fitting is made of brass for corrosion resistance and mechanical strength, offering a durable connection point between plastic piping and threaded fittings. Its design ensures a secure threaded seal and reduces the risk of leaks when installed with appropriate sealing materials. Compatibility with RAUTITAN LX systems simplifies integration and maintains system integrity across plumbing and heating circuits.
Suitable for
Connecting 25 mm polymer pipe to R 1/2" external threaded valves and fixtures
Radiator and boiler connections in hydronic heating systems
Domestic hot and cold water supply lines requiring threaded interfaces
Retrofit or new-build installations using RAUTITAN LX piping
Key specifications
Material: brass
Pipe connection size: 25 mm (compatible with RAUTITAN LX polymer pipe)
Thread type: R 1/2" external (male) thread
Connection type: polymer-to-thread transition fitting
Application: plumbing and heating systems (hot and cold water, hydronic heating)
How to use
Prepare the 25 mm polymer pipe by cutting it square and deburring the end. Insert the pipe into the fitting according to RAUTITAN LX system instructions and secure it using the recommended pressing or connection method for that system. Apply appropriate thread sealant (e.g., PTFE tape or liquid sealant) to the male thread before connecting to the corresponding threaded valve or fixture. Tighten the threaded connection to the torque recommended for the installed components, taking care not to overtighten and to preserve thread sealant effectiveness.
Usage recommendations
Use this REHAU brass transition fitting within its rated temperature and pressure limits as specified by the RAUTITAN LX system documentation. Always follow local plumbing codes and manufacturer guidelines for installation, pressure testing, and maintenance. Verify material compatibility and use proper sealing techniques on threaded joints to ensure long-term leak-free performance.
