## Long description

REHAU transition fitting RX 16x3/4" M threaded in bronze is a connector designed to join RAUTITAN polymer piping to a 3/4" threaded metal connection. The fitting provides a secure transition between plastic system pipe and conventional threaded fixtures or valves, intended for use in potable water and heating installations when installed according to relevant standards and local regulations.
Advantages
The bronze construction offers corrosion resistance and mechanical strength suitable for mixed-material assemblies. The design ensures a tight, leak-resistant connection when combined with the RAUTITAN polymer pipe system and appropriate sealing materials. Compact dimensions simplify installation in confined spaces, and the tested interface reduces the need for additional adapters when connecting to standard 3/4" threaded components.

How to use
Prepare the RAUTITAN polymer pipe according to the manufacturer's cutting and end-preparation instructions. Insert and fix the pipe into the fitting following the RAUTITAN system procedure, ensuring correct insertion depth and any required pressing or assembly step.

Verify the assembled connection for leaks and perform pressure testing consistent with the installation standards for potable water or heating systems.
Usage recommendations
Use only with RAUTITAN-compatible polymer pipe and components, and follow REHAU installation guidelines and local codes. Select compatible sealing materials for the 3/4" thread and avoid over-tightening to prevent thread or fitting damage.
