What is Cross Bend 25mm RAKtherm PPRc ?
A Cross Bend 25 mm RAKtherm PPRc PN 25 is a specialized bridge (crossover) fitting used in PPR piping systems. It allows one 25 mm PPR pipe to pass over another pipe without making direct contact or requiring additional elbows. This helps maintain a neat piping layout while minimizing pressure loss and saving installation space. It is commonly used in hot and cold potable water systems and HVAC piping networks.

Features
- Manufactured from food-grade, non-toxic PPR material.
- Corrosion, rust, and scale resistant.
- Smooth internal surface minimizes pressure loss.
- High resistance to chemicals and mineral deposits.
- Excellent thermal insulation compared with metal fittings.
- Leak-free socket fusion joints.
- Low maintenance with long service life.
- Suitable for concealed and exposed installations.
Applications
The 25 mm Cross Bend is commonly used in:
- Residential hot and cold water plumbing
- Commercial building water distribution
- Hospitals and healthcare facilities
- Hotels and apartments
- HVAC chilled water systems
- Heating water circulation
- Industrial water supply
- Water treatment and filtration systems
- Food processing and pharmaceutical facilities where hygienic piping is required.
Installation Method
- Cut the 25 mm PPR pipe square using a pipe cutter.
- Clean the pipe ends and fitting sockets.
- Heat both the pipe and Cross Bend using a calibrated PPR socket fusion welding machine (typically around 260°C).
- Heat for the recommended time according to the pipe diameter.
- Insert the pipe fully into the fitting without twisting.
- Hold the joint steady until it cools naturally.
- After completing the system, perform a hydrostatic pressure test before commissioning.
Typical Uses
The Cross Bend is used when:
- Two pipe lines must cross each other.
- Avoiding unnecessary elbows and offsets.
- Maintaining smooth water flow.
- Saving installation space inside walls or ceilings.
- Organizing complex plumbing layouts.
- Crossing hot and cold water lines safely.
Advantages
- Reduces the number of fittings required.
- Maintains better hydraulic performance.
- Faster installation.
- Strong fusion-welded connection.
- High pressure and temperature resistance.
- Long operational life.
- Hygienic for drinking water applications.
- Maintenance-free after correct installation.
Suitable Systems
- Hot water supply
- Cold water supply
- HVAC chilled water
- Underfloor heating
- Central heating
- Compressed air (where permitted by system design)
- Industrial fluid distribution
- Potable drinking water systems.
Good Installation Practices
- Use only a calibrated PPR fusion welding machine.
- Do not overheat the fitting during welding.
- Ensure proper alignment before fusion.
- Allow joints to cool naturally—do not force cooling with water.
- Support pipework adequately to prevent mechanical stress.
- Pressure-test the complete installation before service.
