What is Female Socket 40×1-1/4″ DADEX PPRc ?
The Female Socket 40×1-1/4″ DADEX PPRc PN 25 is a polypropylene random copolymer (PPRc) fitting designed for HVAC systems and hot/cold water supply. It connects PPRc pipes to threaded metal components, ensuring leak-free, durable, and pressure-resistant joints. Rated PN 25, it can withstand pressures up to 25 bar, making it suitable for high-demand applications.

⚙️ Installation
- Preparation
- Cut PPRc pipe squarely using a pipe cutter.
- Clean pipe ends to remove dust/oil.
- Fusion Welding (Socket Fusion)
- Heat pipe and socket with a fusion welding machine at ~260°C.
- Insert pipe into socket until marked depth.
- Allow joint to cool naturally.
- Threaded Connection
- Use PTFE tape on the brass threads.
- Connect to metal fittings (valves, pumps, manifolds).
- Avoid over-tightening to prevent cracking.
🛠️ Usage
- Hot & Cold Water Supply: Domestic and commercial plumbing.
- HVAC Systems: Chilled water, heating loops, fan coil connections.
- Industrial Applications: Chemical-resistant piping for non-aggressive fluids.
- Advantages:
- Corrosion-free compared to metal fittings.
- High pressure and temperature resistance.
- Long service life (50+ years under normal conditions).
- Hygienic and safe for potable water.
⚠️ Key Considerations
- Ensure proper fusion welding for leak-proof joints.
- Use thread sealant (PTFE tape) for brass connections.
- Avoid mixing with low-quality fittings to maintain system integrity.
- PN 25 rating means it is suitable for high-pressure systems, but not for steam lines.
