Back Restrain


Iplex has developed RestrainTM PVC-U sewer pipe specifically for gravity sewer applications utilising trenchless techniques for the installation, repair or replacement of underground infrastructure. RestrainTM is a rubber ring jointed PVC-U pipe, with a threaded spigot and socket, which provides immediate axial capability during installation.


The threaded spigot and socket provides immediate axial restrain. The rubber ring seal is seated in a groove behind the spigot thread to ensure that the rubber sealing ring is not dislodged during installation.

Restrain sewer pipe is compatible with both solvent welded and rubber ring jointed DWV PVC-U sewer pipe and fittings conforming to AS/NZS 1260.
