Recommended Applications
Conduit Extension: Joining 3-metre conduit pipes to create longer continuous runs
Industrial Installations: Heavy-duty HMS grade for factories, warehouses, and high-stress environments
Commercial Buildings: Office spaces, retail stores, and commercial complexes requiring reliable connections
Residential Wiring: Concealed and surface conduit systems in homes and apartments
Repair & Maintenance: Replacing damaged conduit sections or extending existing installations
Multi-Story Buildings: Long vertical and horizontal conduit runs requiring multiple joints
Installation Guidelines
Prepare Pipe Ends: Cut conduit pipes square using a hacksaw or pipe cutter; deburr and clean both pipe ends thoroughly
Dry Fit First: Test-fit the collar on both pipe ends to ensure proper sizing and alignment before applying solvent
Apply Solvent Cement: Use VIP PVC solvent on both pipe ends and inside both collar sockets; work quickly as solvent sets fast
Insert and Align: Push both pipes firmly into the collar simultaneously; rotate slightly to ensure even solvent distribution and hold for 30 seconds
Allow Curing: Wait 24 hours before pulling cables or applying stress to the joint; support the joint area during curing to prevent misalignment
