25 mm
Piping of 25 mm diameter is one of the most versatile and widely used dimensions for compressed air networks. It stands out for high capacity, easy assembly and broad compatibility with other diameters. It suits production lines, operations with a larger number of air tools and networks in industrial halls.

25 mm – a reliable solution for medium-sized plants
With its 25 mm diameter, the piping can efficiently feed several workstations at once without any significant pressure losses. Compared with smaller versions such as 22 mm or 20 mm, it provides higher volumetric air flow and thus more headroom for the future.
Systems in this dimension allow fast assembly without welding or gluing – most couplings work on a push-in principle that gives a firm, tight joint. They also come apart easily, so the system can be modified or extended at any time.
🔹 Main advantages:
- High air flow while keeping compact dimensions
- Durable materials – plastic and aluminium versions
- Compatibility with larger and smaller diameters – 28 mm or 22 mm, for example
- A wide choice of fittings and accessories – from couplings to threaded adapters
A modular system with headroom for the future
The 25 mm system suits not only new installations but also an extension branch off main routes of larger dimensions such as 32 mm or 40 mm. It thus allows a stable, capable network with clear structure and the option to connect various technologies and take-off points.
The complete offer includes piping, push-in couplings, threaded outlets, mounting elements and outlet boxes – all with an emphasis on fast, trouble-free assembly.
