Sealing oPVC Networks Across the Globe
PVC and oPVC pipes are used in the construction of vast networks of water and sewer piping systems around the world. It is essential that these pipes convey various fluids without leakage through joints, while preventing external materials such as ground water (inflow/infiltration) and soils from migrating into the pipe through faulty joints.
The **WRM Pressure Lock Seal** makes this joining process possible while ensuring seal integrity for the full system life. The seal is incorporated into the pipe by the oPVC pipe manufacturer, allowing installers to join pipes at the site easily and securely without incorrect seal fitment.
Pipe Assembly Instructions
Follow these 4 critical steps for secure oPVC jointing.
Chamfer Spigot
Chamfer the spigot end at a 12° to 15° angle to ensure smooth insertion into the socket without displacing the rubber ring.
Clean Socket
Thoroughly clean the socket bell and inspect the pre-locked pressure seal to ensure no sand, grit, or debris is present.
Apply Lubricant
Apply a non-solvent based lubricant uniformly to the chamfered spigot end before assembly to minimize insertion friction.
Push & Lay
Slide the spigot into the socket, compressing the sealing lip. Always lay pipes in accordance with applicable engineering standards.
