Green PPR internal thread sleeve — 110mm x 4in — Water pipe connection
Product Description
A 110 mm (4 in) green polypropylene (PPR) internal thread sleeve designed for joining large-diameter PPR pipes with standard metal threaded or screwed fittings. It provides a practical solution for transitioning between PPR pipe thermal welding and threaded connections, facilitating the integration of metal components within water distribution networks.
Key Features
- Made of PPR material with good resistance to corrosion and rust.
- It allows direct connection with standard metal threaded connections.
- Polished design for easy thermal welding with PPR pipes.
- Green color to distinguish them within pipe systems.
- Suitable for use in cold and hot water networks (according to system specifications).
Technical specifications
- Type: PPR internal tooth sleeve
- Size: 110 mm x 4 inches (nominal)
- Color: Green
- Intended use: Transition between PPR welding and threaded connection
Common uses
- Domestic and industrial drinking water networks.
- Heating and hot water systems (according to system specifications).
- Connecting metal components such as valves or threaded fittings within a PPR piping system.
Basic installation instructions
- Make sure the sleeve size matches the pipe diameter and threaded connections.
- Cut the pipe ends at a right angle and clean them of dirt and oil.
- Use the appropriate heat welding machine to attach the sleeve to the PPR pipe according to the manufacturer's instructions.
- After cooling, tighten the metal threaded connection securely without excessive tension to avoid damaging the plastic threads.
- Test the system under pressure to ensure there are no leaks.
Maintenance tips
- Avoid overtightening the connections during installation.
- Check the connection points periodically to ensure there are no leaks or cracks.
- Use compatible spare parts and components to maintain the life of the system.
If you wish, I can add a detailed specifications table or installation illustrations.
