John Guest Speedfit products blend push-fit and multi-seal technology for a reliable leak-proof connection. Simple to install and no tools are required when installing or demounting fittings, making it easy to manoeuvre in tight spaces or readjust joins. Speedfit's extensive choice of plastic, brass and chrome fittings, tap connectors, valves and flexi hoses gives you everything you need to complete the job in no time. By combining these products with plastic push-fit pipe, you can create a truly efficient plumbing system. Our pex pipe is made of 5 layers, the centre of which is a blue coloured oxygen barrier which prevents the ingress of air into the system, reducing the effect of corrosion on metal components. Due to its low thermal conductivity, when carrying hot water, Speedfit pipe is cooler and therefore safer to touch. Note: JG Speedfit pipe inserts must be used.
