## Long description

REHAU transition fitting MX 16 x 3/4" G male RAUTITAN is a connector designed to join RAUTITAN polymer pipe with a standard 3/4" G male threaded metal fitting. Intended for potable water and heating systems, the fitting provides a compact and sealed connection between a 16 mm RAUTITAN pipeline and a threaded fixture. The design supports straightforward installation in domestic and light commercial plumbing, repair and retrofit tasks where reliable transitions between polymer piping and threaded components are needed.
Advantages
The transition fitting offers a corrosion-resistant polymer-to-metal connection that maintains water tightness and mechanical stability under normal operating conditions. Its push-fit-style or compression-compatible end for the 16 mm RAUTITAN pipe ensures consistent alignment and sealing, while the 3/4" G male thread matches common valves, radiators or fittings. The compact form factor simplifies access in confined installations and reduces the need for additional adapters.
Suitable for (tasks / use cases)
 Connecting 16 mm RAUTITAN polymer piping to 3/4" threaded valves or fixtures
 Domestic potable water supply and heating circuits
 Repair and retrofit of existing installations with threaded components
 Light commercial plumbing where polymer-to-thread transitions are required
Key specifications
 Pipe connection diameter: 16 mm (RAUTITAN system)
 Thread type and size: 3/4" G male thread
 Material: polymer transition body with metal threaded end (combination construction)
 Application: potable water and heating systems
 Connection type: transition fitting for polymer-to-threaded metal components
How to use
Cut the RAUTITAN 16 mm pipe squarely and deburr the end before insertion. Depending on the specific RAUTITAN connection method, insert the pipe into the fitting until it seats fully and secure according to RAUTITAN installation instructions (push-fit, compression sleeve, or crimping method as applicable). Tighten the 3/4" G male threaded end into the mating threaded component using appropriate tools and thread sealant or tape if required by the installation practice. Verify the connection for alignment, then pressure-test the system according to local regulations and manufacturer guidelines.
Usage recommendations
Use this transition fitting only with compatible 16 mm RAUTITAN polymer pipes and standard 3/4" G threaded components. Follow RAUTITAN installation instructions and local plumbing codes for preparation, connection method, and pressure testing. Avoid excessive mechanical stress on the joint and protect the fitting from exposure to open flame or aggressive chemicals during installation.
