What is Male Socket 90×3″ RAKtherm PPRc ?
Male Socket 90×3″ RAKtherm PPRc PN 25 is a heavy-duty transition fitting used to connect a 90 mm PPR-C pipe to a 3-inch male threaded connection. It combines a heat-fusion PPR body with a corrosion-resistant brass male threaded insert, making it suitable for hot and cold water distribution, HVAC systems, and industrial water networks.
Description
The fitting is manufactured from Polypropylene Random Copolymer (PPR-C) and incorporates a brass male thread. One side is socket-fused to the PPR pipe, while the threaded side connects to valves, pumps, meters, manifolds, tanks, and other female-threaded equipment. This design provides a strong, leak-proof transition between plastic piping and metallic components.

Installation Procedure
- Cut the 90 mm PPR pipe squarely using a pipe cutter.
- Clean the pipe end and fitting socket.
- Heat both pipe and fitting using a calibrated PPR fusion welding machine.
- Insert the pipe into the socket without twisting and allow cooling.
- Apply PTFE thread seal tape to the 3-inch male thread.
- Screw the fitting into the female-threaded valve, pump, or equipment.
- Tighten carefully using appropriate tools without over-stressing the brass insert.
- Conduct a pressure test before commissioning the system.
