## Long description

Compression reducing coupler Comap 50x4–40x3.5 is a mechanical press fitting designed to join pipes with outside diameters 50 mm (wall thickness 4 mm) and 40 mm (wall thickness 3.5 mm). Intended for use in heating, plumbing and potable water systems, the coupler creates a sealed transition between the two pipe sizes and is compatible with press-connection tools and procedures. The compact design simplifies the adaptation of existing pipelines or the connection of new sections where a reduction in pipe diameter is required.
Advantages
The coupler provides a reliable seal using compression and press technology, reducing the risk of leaks when installed according to recommended practices. Its construction ensures a compact footprint and consistent mechanical strength at the joint. The product is suitable for use with commonly applied press tools and enables faster installation compared to traditional soldering or threaded connections.
Suitable for (tasks / use cases)
Adapting pipe size from 50 mm (4 mm wall) to 40 mm (3.5 mm wall) during installation or repair
Creating transitions in heating and radiator circuits
Plumbing systems for potable water where a mechanical press connection is required
Retrofit projects and system modifications that require a compact reducing connection
Key specifications
Connection type: compression/press reducing coupler
Pipe outer diameters supported: 50 mm and 40 mm
Pipe wall thickness compatibility: 4 mm (for 50 mm) and 3.5 mm (for 40 mm)
Material: designed for metal pipe press systems (follow manufacturer tool compatibility)
Application areas: heating, plumbing, potable water systems
How to use
Ensure pipe ends are clean, free of burrs and cut squarely. Slide the coupler onto the larger or smaller pipe end as required and position so the joint aligns with the coupling’s marking or stop. Use the appropriate press tool and jaw for the material and pipe dimensions, and perform the press operation according to the press tool manufacturer’s instructions. After pressing, verify the mechanical connection visually and by pressure-testing the system where applicable.
Usage recommendations
Confirm compatibility of the press tool and jaws with the coupler and indicated pipe dimensions. Observe local standards and codes for potable water and heating installations, and perform pressure testing after installation to validate the seal.
