Applications:

• Sealing vent pipes through metal or tiled roofing
• Use with vent cowls for complete above-roof assemblies
• Commonly installed in sewerage, stormwater, greywater, and blackwater systems

Installation & Material Notes:

• Pipe fits through the apron; apron base is integrated into roofing material
• Use with solvent cement joints (SCJ) for strong, watertight bonding
• Requires 24-hour cure time for full mechanical strength
• Constructed from PVC-U, known for:
• High chemical resistance
• Excellent durability
• Low maintenance
• Resistance to biological growth

System Compatibility:

• Fully compatible with all DWV PVC-U piping systems
• Works alongside a wide range of fittings from 40mm to 150mm
