Wavin Hep2O Polybutylene Barrier Pipe Coil 22mmx25m White HXX25/22W is the professional's choice for domestic water distribution and central heating systems. This high-performance solution combines 30+ years of innovation with advanced features like In4Sure™ joint recognition and unique straight-coil technology.Designed, manufactured and assembled in Doncaster, UK, Hep2O is WRAS approved and delivers fast installation, secure connections and peace of mind.

• Unique Straight Coil Technology: Unlike other plastic materials that act like a spring, Hep2O pipe remains straight once uncoiled, making handling and installation significantly easier.
• In4Sure™ Joint Recognition: Features a unique 'rumble' sensation when the pipe is fully inserted, providing immediate confidence in a secure joint.
• Integrated EVOH Barrier Layer: Hep2O barrier pipe incorporates an oxygen diffusion barrier that prevents oxygen from entering the system through the pipe wall. This reduces the risk of corrosion in metal components like radiators and boilers, ensuring the long-term health and efficiency of the entire heating circuit.
• High Flexibility for Easy Cabling: Highly flexible polybutylene allows the pipe to be easily 'cabled' around obstructions and through joists, reducing the number of joints required.
• Reduced Installation Time & Cost: Because 'cabling' requires fewer joints, the system is faster and more cost-effective to install than traditional rigid metal alternatives.
• Corrosion & Scale Resistant: Plastic construction ensures no scale build-up and zero risk of corrosion, leading to a longer system lifespan.
• No Naked Flames Required: The push-fit connection eliminates the need for soldering, making the site safer and reducing fire risks during installation.
• Quieter & More Efficient: Naturally quieter in operation than metal systems; the pipe is cooler to the touch and experiences less heat loss.
• WRAS Approved and meets the mechanical performance requirements of BS 7291 Class S for polybutylene piping systems.
• 50-year system guarantee when installed in accordance with Wavin guidelines
