MAGNAPLAST masonry sleeve for external PVC-U sewer 110/240 mm

MAGNAPLAST masonry sleeve for external PVC-U sewer 110/240 mm is a purpose-built passage element that enables a sealed transition for drainage and waste pipes through masonry, external walls or utility shafts. Designed for use with external PVC-U sewer systems, the sleeve accommodates pipe connections in two diameters and provides a structured, durable way to protect the pipe penetration while maintaining a reliable seal against soil, water and debris.

Advantages

The sleeve is constructed to resist common external conditions and to ensure stable positioning of the connected PVC-U pipes. Its design supports quick alignment and offers a secure fit for the larger and smaller connection diameters, reducing the need for additional on-site adapters. The product helps maintain the waterproofing and integrity of wall penetrations while simplifying installation and later maintenance access.

Suitable for

• External building walls where PVC-U sewer pipes penetrate
• Boundary walls with drainage or waste pipe transitions
• Utility shafts, service ducts and manholes requiring sealed pipe passages
• Applications where a change between pipe diameters or a protective casing is needed

Key specifications

• Compatible connection diameters: 110 mm and 240 mm
• Intended for use with external PVC-U sewer systems
• Application: masonry and wall penetrations for drainage and waste piping
• Provides sealed and structured passage for pipes through walls
• Durability suited to outdoor installation conditions

How to use

Position the masonry sleeve in the prepared opening within the wall or shaft so that the appropriate connection ends align with the incoming and outgoing PVC-U sewer pipes. Ensure the sleeve is centered and level before fixing. Connect the PVC-U pipes into the sleeve using the recommended solvent-weld, push-fit or mechanical joint method appropriate for the pipe system in use, and verify that joints are secure and sealed. After pipe installation, complete surrounding wall sealing and any required insulation or protective coatings in line with local building practices to maintain the integrity of the penetration.

Usage recommendations

Verify compatibility with the specific PVC-U pipe profiles and jointing methods used on site. Prepare a correctly sized and clean wall opening, check alignment prior to final fixing, and follow local regulations for external sewer penetrations and waterproofing to ensure long-term performance.
