Hep2o is an innovative, flexible, push-fit plumbing system especially developed for use by architects, designers and professional installers. The hep2o system is particularly suitable for domestic hot and cold water supply, including potable water, and central heating. The system comprises flexible 'straight coil' polybutylene pipework connected to polybutylene fittings that incorporate an integral push-fit mechanism. Unlike other forms of coiled plastics pipes, hep2o pipes utilising 'straight coil' technology do not return to their coiled state when uncoiled from their convenient smartpacktm dispensers but instead remain straight with no loss of flexibility. These characteristics provide a significantly faster, safer and more cost effective installation when compared to rigid pipe systems. We offer a range of fittings which can be used to connect hep20 pipes to standard 1/2" and 3/4" threads.
