## Summary description

## Long description

REHAU Rautitan RX transitional fitting with external thread 20 – R 1/2 is a lead‑free brass adapter intended to connect polymer pipe systems to threaded components. Finished in brown to match Rautitan RX systems, this fitting is designed for potable water installations and provides a corrosion‑resistant mechanical connection between plastic piping and valves, taps or other threaded fixtures.
Advantages
The fitting is manufactured from lead‑free brass for compliance with drinking water requirements and offers reliable mechanical strength for long‑term use. Its brown finish provides visual compatibility within Rautitan RX installations. The external thread ensures simple and secure connection to standard R 1/2 threaded components while the transitional design allows direct joining of polymer pipes to metal fixtures without additional adapters.
Suitable for
 Connecting polymer pipes (Rautitan RX) to R 1/2 threaded valves, taps and fittings
 Potable water distribution in residential and commercial buildings
 Plumbing repairs and retrofits where a durable threaded transition is required
When it may not be suitable
This fitting is intended specifically for transitions between polymer pipe systems and standard R 1/2 threaded components. It may not be suitable for systems that require different thread sizes or for non‑drinkable media with chemical compatibility concerns. Do not use this fitting in applications that demand stainless steel or other specific materials for aggressive fluids or very high temperatures beyond typical domestic hot water ranges.
Key specifications
 Connection type: transitional fitting with external thread
 Pipe end size: 20 mm (for polymer pipe connection)
 Thread size: R 1/2 (external thread)
 Material: lead‑free brass
 Finish/color: brown
 Application: potable water, plumbing and heating distribution
How to use
Prepare the polymer pipe end according to the Rautitan RX installation instructions (cut square, deburr, and insert required insert if specified by the system). Screw the fitting into the R 1/2 threaded component by hand, then tighten with an appropriate wrench to the torque recommended by REHAU or project specifications. Ensure pipe insertion depth is correct and any system‑specific sealing or crimping process is completed following manufacturer guidelines. After installation, pressure‑test the system to verify leak‑free connections before commissioning.
What to consider before purchase
 Confirm compatibility with the polymer pipe system (Rautitan RX) and required pipe outer diameter (20 mm)
 Verify that R 1/2 external thread matches your mating component
 Check temperature and pressure requirements of your system to ensure brass material is adequate
 Ensure local regulations permit lead‑free brass fittings for potable water installations
Usage recommendations
Install and test fittings according to REHAU installation instructions and local plumbing codes. Use appropriate tools and follow recommended torque values. For long service life, avoid exposure to aggressive chemicals and verify compatibility with system fluids and operating conditions.
