20 mm
Compressed air networks of 20 mm diameter are a popular choice for workshops, service operations and smaller production lines. They offer sufficient air flow while keeping compact dimensions and simple installation with no welding or gluing.

A balanced system for versatile use
The 20 mm diameter is the ideal choice where 15 mm or 18 mm piping is no longer enough. It serves excellently for connecting several workstations, air tools, or for carrying air over shorter distances with higher draw.
Thanks to its low weight, high mechanical resistance and a wide accessory range, this system also suits variable networks that are modified or extended over time.
🔹 Advantages of the 20 mm system:
- Suitable for more extensive workshop networks
- Safe, firm and repeatedly demountable joints
- Can be linked to other diameters – 22 mm or 25 mm, for example
- Fast, clean installation – with no needless downtime
Easy design and expandability
The 20 mm piping system is fully compatible with the other sizes, so it easily connects to a main line of 32 mm or 40 mm and branches out into smaller lines using reducing fittings. The result is a flexible, clearly arranged system that adapts to any operation.
The range includes aluminium and plastic tubes, push-in couplings, outlet boxes, mounting accessories, reducers and adapters. All designed to make assembly fast, tidy and reliable.
