PE Restraint Couplings
PE Restraint Couplings are designed to provide a full restraint connection for polyethylene pressure pipes and are suitable for use in potable water; non-potable water and wastewater pipelines.
The couplings have a grip ring that, when fully tightened, secures the pipe joint to provide a full restraint connection.
Full restraint system for PE pressure pipes.
Corrosion resistant materials suitable for drinking water and wastewater applications.
Push-fit connection for ease of installation.
Can be installed without disassembling making installation faster and easier.
Easy to dismantle.
