JG Speedfit Polybutylene Barrier Pipe is for longer runs of pipe where a softer pipe material is advantageous. The flexible pipe is easy to handle and once removed from the coil will retain its shape and keep straight and flat. It’s ideal for using to cable through joists. The pipe has 5 layers with the centre being an oxygen barrier to prevent air entering the system and causing corrosion. The pipe is lead free and non-toxic and prevents scale build up. It's suitable for use in central heating systems.
