## Long description

The MAGNAPLAST Coupling Internal Double D75 PP is an internal double coupling designed for joining two pipes or pipe sections with a nominal diameter of 75 mm. Manufactured from polypropylene (PP), the fitting is intended for use in drainage and ventilation systems where a compact, corrosion-resistant connection is required. The coupling provides a snug internal fit to create a leak-resistant joint between compatible plastic pipes and is suitable for repair, retrofit and new-build installations that require lightweight components with chemical resistance.
Advantages
This internal double coupling is made from polypropylene, offering chemical and corrosion resistance while remaining lightweight for easier handling during installation. Its internal design allows for a streamlined external profile, reducing interference with surrounding structures. The coupling provides a reliable seal when used with compatible pipe materials and installation methods, and its standardized 75 mm nominal diameter simplifies selection and replacement in existing systems.
Suitable for
 Joining two 75 mm nominal diameter plastic pipes in drainage systems
 Connections in ventilation ducting where compatible materials are used
 Repair and retrofit of existing plastic pipe runs
 New construction pipe installations requiring chemical-resistant fittings
Key specifications
 Material: polypropylene (PP)
 Type: internal double coupling
 Nominal diameter: 75 mm
 Application: drainage and ventilation systems
 Properties: lightweight, chemical and corrosion resistant
How to use
Prepare pipe ends by cutting square and removing burrs to ensure a smooth fit. Verify that the mating pipes are compatible with polypropylene and have the correct 75 mm nominal diameter. Insert each pipe end into the coupling until it seats fully, following any depth marks or manufacturer guidance. Where required, apply appropriate sealing methods compatible with the pipe material and system (for example, compatible rubber seals or solvent welding if specified by the pipe manufacturer). Inspect the connection visually and, where applicable, perform a pressure or leak test in accordance with local codes and project requirements.
Usage recommendations
Use the coupling only with compatible plastic pipes of matching nominal diameter and follow manufacturer recommendations for sealing and testing. Avoid exposure to unsupported mechanical loads or prolonged UV exposure; where pipes are externally exposed, provide protection or select UV-stabilized materials. For systems conveying aggressive chemicals or operating at elevated temperatures, verify material compatibility and use fittings certified for the specific conditions.
