1
Cut, Chamfer & Clean
Ensure the uPVC pipe is cut absolute square. Remove running edge burrs completely and wipe the pipe end and internal fitting socket clean from soil dust or oil moisture grains.
-
2
Apply BPI Solvent Cement
Spread a uniform, liberal layer of BPI Industrial Heavy-Duty Solvent Cement to both the exterior pipe end layer and the interior entry slot of the fitting socket.
-
3
Insert & Twist Connection
Push the pipe firmly straight into the receiving fitting slot while executing a quarter turn (90° twist) to spread the cement uniformly across the mesh. Hold locked for 30 seconds.
-
4
Curing Matrix Lifespan
Allow the unified molecular bond joint to cure safely undisturbed before passing water test pressures. Refer to cement packages for precise dynamic environmental curing hours.
Highly Recommended
For achieving 100% leak-proof, high-pressure lifetime joints, always utilize BPI Heavy-Duty Solvent Cement. Expressly engineered for our complete uPVC pressure pipe ranges.
