The PP-r internal-external reducing coupling is a polypropylene fitting designed to connect pipes of different diameters with both female and male threads. It is used in hot and cold water supply systems, as well as in domestic and industrial pipelines requiring combined threaded connections.
Key features of the PP-r internal-external coupling:
- Material — PP-r polypropylene with metal inserts for secure threaded connections.
- Connection type — one side with female thread, the other with male thread.
- Application — transition between fittings or pipes of different standards.
- Use cases — plumbing, heating, and technical piping systems.
- Installation method — combined: threaded connection and heat welding.
The PP-r internal-external coupling is a versatile solution for assembling threaded pipeline sections, ensuring reliable sealing and long service life.
