## Long description

REHAU RAUTITAN RX transition fitting with external thread 25 mm to R 3/4 is a lead-free brown fitting designed for RAUTITAN RX piping systems. It provides a mechanical connection from a 25 mm polymer pipe to an R 3/4 threaded outlet, intended for potable water and heating installations. The fitting is suitable for use in repair, extension or new-build plumbing work where a secure threaded interface is required.
Advantages
This transition fitting is lead-free and manufactured to integrate with RAUTITAN RX pipe systems, offering reliable mechanical connection and a threaded outlet for easy attachment of valves or fixtures. The brown finish matches RX system components, and the external thread simplifies linking polymer piping to standard threaded plumbing parts. The design supports potable water and heating applications and is intended to provide durable performance within recommended temperature and pressure ranges for RAUTITAN RX systems.
Suitable for
 Converting a 25 mm RAUTITAN RX pipe end to an R 3/4 threaded outlet
 Repairing or replacing a threaded connection in domestic potable water systems
 Creating connections to valves, taps or heating components with R 3/4 female threads
 Extensions and modifications in residential heating and plumbing installations
When it may not be suitable
This fitting is specifically made for RAUTITAN RX polymer pipe systems and may not be compatible with unrelated piping materials or proprietary connection types. It is not intended for use where codes or applications require metal-only fittings, or for systems operating outside the temperature and pressure ranges specified for RAUTITAN RX components.
Key specifications
 Pipe connection size: 25 mm (RAUTITAN RX)
 Thread type: external thread to R 3/4
 Material: lead-free polymer/plastic (brown finish)
 Intended media: potable water and heating systems
 Application: mechanical transition from polymer pipe to threaded outlet
How to use
Prepare the 25 mm RAUTITAN RX pipe according to RAUTITAN installation guidelines, ensuring a clean, square cut and correct pipe end preparation. Insert and secure the transition fitting following the system's joining method (e.g., press-fit or compression depending on RX variant) to achieve a leak-free mechanical connection. Tighten the R 3/4 external thread into the corresponding female threaded component using appropriate sealing tape or compound where required by local practice, taking care not to overtighten and damage the fitting.
What to consider before purchase
 Confirm compatibility with RAUTITAN RX 25 mm pipe and the specific RX joining method used in your installation
 Ensure R 3/4 female thread on the mating component for a correct fit
 Verify that material properties (lead-free polymer) meet local plumbing codes for potable water
 Check temperature and pressure requirements of your system against RAUTITAN RX component limits
Usage recommendations
Use this REHAU RAUTITAN RX transition fitting in accordance with RAUTITAN installation instructions and local plumbing regulations. Employ proper pipe preparation tools, recommended joining techniques for RAUTITAN RX, and appropriate thread sealing methods for R 3/4 connections to ensure a reliable, long-term installation.
