What is Elbow male 25×1/2″ Brass DADEX PPRc ?
The Elbow Male 25×1/2″ Brass DADEX PPRc PN25 is a polypropylene random copolymer (PPRc) elbow fitting with a brass male threaded insert. It connects 25mm PPRc pipes to ½” female-threaded components (like valves, taps, or equipment) in HVAC systems and hot/cold water supply lines, designed for high-pressure applications (PN25 rating).

🛠️ Installation
- Pipe Preparation: Cut and clean PPRc pipe ends.
- Fusion Welding: Heat the PPRc end with a welding machine and join to the elbow body.
- Thread Connection: Screw the brass male thread into a female-threaded fitting (tap, valve, or equipment). Use PTFE tape for leak-proof sealing.
- Alignment: Ensure correct orientation of the elbow to avoid stress.
- Support: Provide adequate pipe clamps/supports to prevent strain on threaded joints.
- Testing: Perform hydrostatic pressure testing after installation.
💡 Usage
- HVAC Systems: Connects PPRc piping to threaded HVAC equipment (chillers, boilers, pumps).
- Hot & Cold Water Supply: Links PPRc pipelines to taps, valves, geysers, and other threaded fixtures.
- Industrial Applications: Suitable for compressed air or chemical-resistant piping where threaded connections are needed.
- Maintenance Points: Ideal for areas requiring disconnection or replacement of equipment.
⚠️ Key Considerations
- PN25 rating ensures suitability for high-pressure HVAC and industrial systems.
- Brass insert provides strength at threaded joints, preventing wear and leakage.
- Thermal expansion of PPRc must be considered in hot water systems.
- Proper sealing with PTFE tape or thread sealant is essential to avoid leaks.
