The Buteline Plumbing System is designed for hot and cold water reticulation
using Polybutene-1 (PB-1) pipe, or for cold water only using Polyethylene
(PE) pipe. It is impor tant to note that while Buteline is one of the leading
brands that are known for their use of Polybutene-1 pipe, ‘Buteline’ is not the
same as ‘Polybutene-1’ - one is a brand, the other is a raw material.
Buteline always represents quality and we only select materials which are
specifically designed for their applications. Both Buteline PB-1 and PE systems
utilise a proven and efficient clamping technique, and are marked with our
copyrighted logo, engravings on our fittings and pipe mar kings at every
1 metre inter val (as pictured).
Due to the well thought-out design of fittings and tools, the Buteline
Plumbing System is difficult to install incorrectly (please refer to ‘The Jointing

proven solution for the conveyance of clean healthy drinking water. With superior temperature and thermal capabilities
compared to other materials, there is no need for lagging – it endures and continues to perform both in low and high
